Comment 26 for bug 591656

I found that this bug had already been reported upstream: https://bugs.freedesktop.org/show_bug.cgi?id=23890. You may register at http://bugs.freedesktop.org and add yourself to the CC-field of that bug report in order to receive updates. It seems they have already figured out what we have figured out here, but I'll link to the attachments here anyway.

The one think I can think about that may accelerate a solution is to git-bisect between 1.1.2 and 1.2.2 to find the commit that introduced this problem. Before that it may be worth reverting the ubuntu-sepcific patches to see if any of those cases the problem.
