Hi Rex and Barry,

This particular instance stands out because it happens every time the
program runs with the Fedora PyQt5 package, and never with the Pypi PyQt5,
which is not something I've seen before. This makes it a bit different from
cases where it might happen occasionally because (for example) a widget was
not given a parent, leading to potential problems during application close.
I do believe this latter case is what you're referring to Barry.

What do I need to do to generate an bug report that will actually be usable
to the Fedora PyQt maintainer? Do I need to install debug packages and run
some kind of debugging tool? It's been a couple of decades since I coded in
C/C++ so my knowledge of these tools is extremely limited.
