I have debug nofork output if needed, saved in a file. Not really, as there is no evidence this is Amarok or Phonon related. If you change the backend while Amarok is running, it is important to restart it, else it will try to continue to use the previous backend and invariably crash :( I change the title accordingly, as this is as wish for a message asking to restart, instead of a crash That makes sense. I meant to quit, but clicked the next song automatically. A warning might have stayed my hand. This is solved since ages, since changing the backend has no effect until Amarok is restarted. |
Application: amarok (2.3-GIT) KDE Platform Version: 4.4.92 (KDE 4.4.92 (KDE 4.5 RC2)) Qt Version: 4.7.0 Operating System: Linux 2.6.32-24-generic x86_64 Distribution: Ubuntu 10.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: changing backends from VLC to Xine. Clicked a track in playlist, and Amarok went nuts, rapidly skipping through tracks until it crashed. I was unable to get a menu to let me quit cleanly. -- Backtrace: Application: Amarok (amarok), signal: Segmentation fault [Current thread is 1 (Thread 0x7f790f294780 (LWP 5776))] Thread 15 (Thread 0x7f78c4564710 (LWP 5782)): #0 pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:162 #1 0x00007f78f6d4d8b2 in Thread () from /usr/lib/libvlccore.so.4 #2 0x00007f7909ac19ca in start_thread (arg=<value optimized out>) at pthread_create.c:300 #3 0x00007f790bfe672d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:112 #4 0x0000000000000000 in ??
