stacktrace of the issue, using GDK_SYNCHRONIZE=1
The issue has been reported on
<a href="https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1211887">https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1211887</a>
The stracktrace has been collected using GDK_SYNCHRONIZE=1 and b gdk_x_error
(the issue started in Ubuntu 13.10, webkit didn't change compared to Ubuntu
13.04 which didn't have the bug so it might be an issue with GTK or cairo...)
