Version: 0.4.0 (using KDE 4.6.5) OS: Linux When I try to play a FLAC file with Amarok using Phonon-VLC I get a floating point exception. VLC on its own and Dragon Player (also using Phonon-VLC) do not crash! Also the FLAC files should be ok. Running them through flac -a does not tell my any errors as far as I can see. Some of the files I created from audio CDs using flac, some others I purchased from magnatune.com. I had similar crashes with the Phonon-Xine backend every now and then month ago. But this crashes stopped to happen at some point. I switched to the VLC backend because the Xine backend stopped to produce any sound and started to crash on every song change/stop (using Amarok). I compiled Amarok from GIT: commit 3513760bfcd3866539084081fa3c1b07295da827 Author: Script Kiddy <scripty@kde.org> Date: Fri Aug 12 08:39:17 2011 +0200 I also compiled Phonon-VLC 0.4.0 myself. I did this because I still use Fedora 14 which uses KDE 4.6.x for which Phonon-VLC 0.4.0 is the last compatible version. While this is provided by Fedora, this version of Phonon-VLC misses some mime types in the list of supported mime types. So I simply added them: https://github.com/panzi/phonon-vlc/tree/module_files_for_kde_4.6 Backtrace: Application: Amarok (amarok), signal: Floating point exception [Current thread is 1 (Thread 0x7f1f234a9880 (LWP 10074))] Thread 14 (Thread 0x7f1f2340e700 (LWP 10077)): #0 0x00007f1f1f41b3b4 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0 #1 0x00007f1f034dd762 in LoopRequest (data=0x2090870) at playlist/thread.c:539 #2 Thread (data=0x2090870) at playlist/thread.c:586 #3 0x00007f1f160cf56c in ??
