Comment 17 for bug 1874096

According to that stackoverflow link, this bug should be fixed in PyQt 5.14, which is the one that I have installed, and I don't have any crashes on exit. packages.ubuntu.org says that eoan has 5.12, which is buggy and shows this problem.

Curiously, we build our binaries with 5.13.1, which according that article is also buggy, but our binaries don't show the issue.

Anyway, not much we can do about it -- it isn't our bug.
