Does it crash if you do not use QtCurve (since the crash is in the deinit process of QtCurve)? (p.s. this is a crash on exit - something asks kamd to quit and QtCurve crashes) (In reply to Ivan Čukić from comment #1) > Does it crash if you do not use QtCurve (since the crash is in the deinit > process of QtCurve)? > > (p.s. this is a crash on exit - something asks kamd to quit and QtCurve > crashes) Qtcurve is the culprit! Setting "Breeze" back does not trigger the crash. I'll edit the title. Similar crash. Here's my backtrace Application: kactivitymanagerd (kactivitymanagerd), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
