Created attachment 338530 [details] dolphin.kcrash It had worked before today's round of minor bumps to qt packages and nepomuk-core. Happens every time it quits.

Well there's nothing about nepomuk in the trace, all points to qt-gui. Maybe that security revbump broke something?
Created attachment 338534 [details] kget.kcrash kget crashes every logoff, so attaching its log too.
Created attachment 338536 [details] kmix.kcrash same with kmix
Can you rebuild qt-gui please? There was a change related to MITSHM extension after the revbump.
No change after rebuild of qt-gui-4.8.4-r1.
OK, seems I was a bit too fast in my conclusion yesterday. The binary built without -fgraphite-identity actually works, after restart. So this bug can be entirely attributed to the usage of -fgraphite-identity and nothing else.
