Bug#620675: amarok's Wikipedia widget leads to a SIGSEGV in libqtwebkit4 whenever a song is played (and the widget is hence updated)
Package: libqtwebkit4
Version: 2.1.0~2011week09-3
Severity: important
I believe the bug is in libqtwebkit4, but it could be amarok's fault.
How to reproduce:
==============
Enable the Wikipedia widget in amarok and play a song.
Here's the backtrace:
================
Program received signal SIGSEGV, Segmentation fault.
