So I decided to work again on that right-click crash bug this Weekend. I started a gdb session with current build this saturday and find out that I had to rebuilt Qt (a special static lib build) with debug info to be ebble to go further in the debug
Here is the (short) gdb sesion
Code:
The program 'Telegram' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
  (Details: serial 1438 error_code 2 request_code 139 minor_code 51)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

So I started rebuilding Qt.... It finished sunday afternoon... Than I had to cleanily recompile Telegram itself (because of changed PCH files)... It ended this monday morning.
So I quickly started a new debug session before going to work... to find out it doesn't crash anymore!

So I just took that binary, stripped it and create a new PND... Qt is a debug build, not a release build, but I don't think the missing optimisation is really important for that type of software.

Build 09

  • Fixed right-click crash

I realy appreciate your Patience and Work with it.
Thank you @ptitSeb
and i tried it and i do not like it to bring you bad News.
Now it crash on animated Gifs.

"WSEGL_InitialiseDisplay: DRI2OpenConnection failed Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed [swscaler @ 0x2d94ab0] No accelerated colorspace conversion found from yuv420p to bgra. ./runscript.sh: line 82: 6007 Bus error ./Telegram "$*"

and the right Click Error is still here:

Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed The program 'Telegram' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue'.

AL lib: (EE) alc_cleanup: 1 device not closed"

I will try to reflash my Pandora and test it again,
Maybe there are some encounters with my other Tests and i try a "clean" Test

Really? Strange, it did work for my (before packaging), I got the local menu comming... .Bbut no idea about animated gif, unless I forgot to add gif in my rebuild of Qt :( . Now that I think of it, yes, that's probably... I need to compile Qt and everything again :'(

I'll do more tests tonight about the right click.

New build on the repo. I have fixed the right-click crash for good this time.

After a lot of debugging and recompiling, it turns out the issue was in the mouse handling using Xinput2.
So, export this QT_XCB_NO_XI2_MOUSE=1 in the runscript fixed the issue.

I don't know if animated gif is still broken (as this is a fresh build). If it's still broken, I'll fallback to build 08 binary..


Build 10

  • Really fixed right-click crash

I'll test it in a few minutes.
[doublepost=1472909535,1472908768][/doublepost]I'm not sure if it was a gif that did it as it crashes before I can see what tried to load, but it was some type of image.

Code:
WSEGL_InitialiseDisplay: DRI2OpenConnection failed
Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed

I must confirm this.
Tried the same with Build8 and same Error there because the animated Gifs.

The right Mouse Click Problem is realy good solved now ;)

Edit:
Google said its an FFMPEG Problem with this Lib inside FFMpeg:
https://www.ffmpeg.org/libswscale.html

@ptitSeb
I found here a Howto solve that:

Edit Edit:
I checked that Link and it seem to simply need a new giflib and FFmpeg Version

Ok, it's not super clear now.

About the crash: does it crash also with Build 08?

About the No accelerared color space: this is a not the issue, just a warning that the conversion between the 2 colorspace will be done by software (and that's fine for the Pandora). The real issue is the "Bus error", but I need a full backtrace to be able to debug. But for that, I need to make a "debug" pnd (non-stripped).

But first, I need an awnser, does it crash with build 08, because I had to impression that this one was not crashing.

Maybe you need a swapfile, it's huge with the debug infos.

Also, don't right click or it will crash (or add QT_XCB_NO_XI2_MOUSE=1 to the already long command line).

Ok, I have uploaded a new version of the Telegram pnd. Still the same link. This one should have debug info on the FFmpeg libs, so the gdb BackTrace should give more details this time, hopefully enough so I can fix it.
