Crash in fglrx, most likely caused by blur and/or contrast effect, see bug #349862, but the backtrace lacks the necessary debug symbols to be sure; you need to install at least kwin-debuginfo.

If it's the same bug, disabling caching in the blur effect *might* prevent this (but we don't know what the actual reason is since fglrx remains opaque)
Comment 2 tneo 2016-02-08 20:14:53 UTC 
Disabling that seems to have a positive effect. I'll monitor it and will get the debug packages as well.
Comment 3 tneo 2016-02-25 11:04:40 UTC 
Since the settings change KWin has been running without any crashes.
