Possibly the destroyed-signal bug fixed a few days ago.

[Tom Goddard]

Without the log this bug would be classified as "Unknown crash" since the Python traceback just shows it was in the Qt event loop. But it looks from the log like it was caused by something that happened immediately after a session was successfully opened -- last log message is "opened ChimeraX session".
