smells like if (!c->readyForPainting()) { QTimer::singleShot(0, this, SLOT(discard())); } would act synchronous (possibly because the eventchain is currently dying?) if (!c->readyForPainting()) { deleteLater(); return; } but we probably got to revert that workaround for other reasons anyway.

IIRC the issue pointed out in comment #1 has been reverted for 4.8.1. So it is quite possible that this crash had been fixed in 4.8.1. In case you are still able to reproduce the issue with 4.8.1, please reopen the bug report. Thanks.
Nope, commit -if actual culprit and Qt behavior- is still in.
