Created attachment 11597 [details] Backtrace of the segfault Backtrace + the value of xkbi->desc, which is NULL. I forgot to mention that I use the debian package of xorg server, of experimental, which is version 1.4,recompiled with -O0 Note that the only 100% way to reproduce this bug is to play a video (with xv) before switching to VT, but it sometimes occurs without playing a video before (Maybe that's a different bug then, as I have not taken stacktraces of that faults). This bug might be related to Bug 12437. As the bug occurs in some keyboard-related code: No matter whether NUM is enabled or disabled under X, the LED on my keyboard is off. It is on as soon as I switch to VT (unless it crashes). This also applies to CAPS-LOCK. However, the internal state is preserved, as THESE THREE WORDS are written with CAPS-LOCK enabled.

The xkb code has improved since and I can't reproduce your problem with the current version. If it still occurs, please attach your log file. I can't reproduce it anymore, as all the xv related issues have been resolved for me. I have another crash bug (on context switch) which occurs very seldomly that might be related to this bug, but I haven't had yet time to really investigate it.

If you can't reproduce it, I guess we can mark it as closed. |
