Sentry Crash Report:

Description Mathias Panzenböck 2011-08-12 15:04:36 UTC 
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:
