Comment 1 Dominik Haumann 2014-06-07 13:08:46 UTC
Can you try to update Qt to version >= 4.8.4 ?

The backtrace doesn't contain any Kate traces, so it's not easy to see what's happening here. Maybe a Qt issue...
Comment 2 Christoph Cullmann 2014-09-09 22:19:03 UTC
We need more info how to reproduce.
