Bug#983031: konqueror segfaults on starting
Le samedi 6 mars 2021, 17:43:11 CET J Rowan a écrit : > On Sat, 6 Mar 2021 14:04:38 +0100 Dear Joe, thanks for taking the time to report the bug and investigate. What the stack tells us is that the crash is in the R300 OpenGL graphics driver, as called by Qt Web Engine that Konqueror uses for the HTML rendering. I cannot reproduce the crash myself on various more recent pieces of hardware, and neither did the team get similar bug reports. So I can see 3 possible causes and (im)possible fixes from the most probable to the least : 1/ The OpenGL driver has a broken code path that is triggered here and should be fixed. 2/ Qt Web Engine calls the OpenGL stack incorrectly in this case and could be fixed. Alternatively it could be made to work around that particular OpenGL driver bug even if we’re in case 1/. 3/ That piece of graphics hardware is (now) broken and the code path makes it visible, nothing we can do about it. If that was the case I would expect the crash not to be reproducible 100% of the time, and here it looks like you can reproduce it so maybe not. Looking the hardware support for that driver you must have a graphics card from the Radeon 9500-9800 series, X300-X600 series or X1050/X1150 from the 2003-2005 era. This driver is in maintenance mode to say the least so I wouldn’t get my hopes too high about a possible fix. However if you want to help diagnose the issue further you could install the dbgsym packages [1] for at least libgl1-mesa-dri, libglx-mesa0, libqt5webenginecore5 and konqueror packages, and rerun the same gdb call so we get the crash stack with the function names and line numbers. If you can confirm whether you get crashes with other programs using 3D rendering besides konqueror, that would be a useful data point. Then we can decide if we want to forward the bug to mesa or Qt. Again be ready to face refusals from both upstreams to work on an issue for such an old piece of hardware. Most opensource projects are understaffed and I have the feeling that reproducing let alone fixing this issue is not going to be an easy task. Also I seem to remember that the R300 driver was made out of reverse engineering or with documentation provided to selected developers under NDA, which is not going to help either… If you don’t have the time or motivation to do the above and dig further I’d still appreciate that you say so, and I’ll just mark this bug as « won’t fix ».

Bug#983031: konqueror segfaults on starting
Hello Joe, this information might not be sufficient for the maintainer. Could you try following to collect some more informations? - install packages: gdb psmisc konqueror-dbgsym - stop all running instances of konqueror: killall konqueror - then start konqueror inside a debugger: gdb -q -ex 'set pagination off' -ex 'run' -ex 'bt' -ex 'detach' -ex 'quit' --args konqueror When the crash happens, a backtrace should be printed. Please forward this output to this bug. More debugging hints can be found here [1]. Kind regards, Bernhard [1] https://wiki.debian.org/HowToGetABacktrace
