Description

Looks like bug #345675, but QSGOpaqueTextureMaterial::setTexture is NOT the current thread here. The backtrace is missing debug symbols for Qt5Quick where the actual crash occurs. In case you are able to reproduce, please install the debug symbols and upload a new crash trace. Whatever gets us there, it segfaults in pthread_cond_wait what would mean either a) broken libthread b) unlocked mutex delivered to pthread_cond_wait c) segfault in other thread and pthread_cond_wait just randomly burps and receives it. Given bug #345675, I bet on (c) It seems the error only occurs when certain window decorations are installed. In my case glowglass-deco causes the problem. Which package contains the right debug symbols for libQt5Quick.so.5? I installed qtquick1-5-dbg, but there is still same information missing.
