Type: Bug
Resolution: Cannot Reproduce
Priority: P2: Important
Fix Version/s: None
Affects Version/s: 4.7.1, 4.7.2, 4.8.0, 5.5.1, 5.7.0
Component/s: Widgets: GraphicsView
Labels:

Environment:
Gentoo linux (x86_64), glibc 2.12.2, KDE 4.5.5, xorg-server 1.7.7, gcc-4.5.2, Qt compiled from source with -O2 -mtune=generic

Arch linux (x86_64), Qt compiled from source with debug symbols

Description

I get a reproducible crash with amarok-2.4.0 on x86_64 linux with Qt 4.7.1 and 4.7.2. It happens randomly (once an hour or so) on track change when playing mp3 files. I tried to disable raster backend but got the same crash.

I use the following applets in amarok: Current Track, Labels, Albums, Similar Artists, Lyrics.

To me it looks like a regression from Qt 4.6.0 (~~QTBUG-5090~~).

Backtrace I made with: gdb --args amarok --debug --sync --nofork
