Bug 266207

Summary: Amarok crashes upon fast song change (possibly gstreamer/pulse?)
Product: [Applications] amarok Reporter: ferahgo.de
Component: generalAssignee: Amarok Bugs <amarok-bugs-null>
Status: RESOLVED UPSTREAM    
Severity: crash CC: gbrlhtclcq, jaedns, phillip.kruger, sebrem

Sentry Crash Report:

Description ferahgo.de 2011-02-13 16:28:32 UTC 
Application: amarok (2.4-GIT)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-22-desktop x86_64
Distribution: "openSUSE 11.4 RC 1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Changing from one song to another. Every once in a while, this leads to a crash. It seems somewhat related to the song changing frequency, meaning: If I "next" a few songs quite quickly one after the other, Amarok crashes. But this also happens "just like that" every once in a while, but _only_ on song switch. This happens with every backend.

- Unusual behavior I noticed:
Afterwards, Plasma Workspace crashes. This however can apparently not be debugged into something useful.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
