Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install debug packages and attach a new backtrace
Argh, sorry about that, I didn't notice....will install the debug symbols and try again.
Okay, got the kwin debug....is this more helpful? Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

There are still debug symbols missing for: - libQt5Quick - r600_dri driver Looking at the incomplete backtrace, I feel this is an r600 DRI driver bug that you could report to developers of that driver.
Well, I can't repro now. I'll get the rest of the symbols and we'll see if it comes up again. I see also that R600 is getting some fixes/updates, so perhaps I'll wait for that update on TW.
