[Interest] Random crash in QtWebkit / Qt 5.3

[Cornelius Hald]

Hi guys!

The crash still happens with the latest RC-snapshot. Only now the
addresses have changed. Can I find the debug symbols for those builds
somewhere? 

This backtrace was done using:
http://qt-mirror.dannhauer.de/snapshots/qt/5.3/5.3.0-RC/2014-05-07_85/qt-opensource-linux-x64-5.3.0-RC_2014-05-06_23-24-27-76.run
