Hi Christian!
[...]

Is there a way to reproduce it? I opened openshot-qt, added a video, clicked
some buttons but it did not crash.

Is it related to upgrade of Qt itself (5.15.2 to 5.15.4) or upgrade of PyQt5
or python3-pyqt5.sip?

Can you install these debug packages and see if stacktrace becomes better?

- python3-pyqt5-dbgsym
- python3-pyqt5.sip-dbgsym
- libqt5core5a-dbgsym
- libqt5gui5-dbgsym

Hi Dmitry,


[...]

I'm unable to reproduce this bug on another machine. So I close this bug.
