--- Comment #4 from Sven Brauch <m...@svenbrauch.de> --- I can reproduce this as well, and I see it with Python too. The backtrace with the new assistant is different: Thread 1 (Thread 0x7f1393626800 (LWP 4533)): [KCrash Handler] #5 0x00007f138c8928e0 in typeinfo name for QObjectPrivate () from /usr/lib/libQt5Core.so.5 #6 0x00007f13936267f0 in ??

It's some kind of memory corruption, but I really don't know where it comes from or why it happens. QTextEdit is always in the backtrace for some reason. -- You are receiving this mail because: You are watching all bug changes.
