I had the latest stable updates installed a couple of nights ago when I was using stellarmate.
Crashes about every 20 minutes or so. The core files are unreadable, at least by me, no stack trace.
I turned on logging, and also ran kstars from the command line and captured stdout and stderr. I saw several messages with this text:[2022-11-19T22:13:57.275 PST WARN ][ default] - Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt.
You must not let any exception whatsoever propagate through Qt code.
If that is not possible, in Qt 5 you must at least reimplement
QCoreApplication::notify() and catch all exceptions there.

Is there some way I can obtain a build of kstars for stellarmate with debug symbols? Then I could provide more detail. Since it appears to be Qt related, it probably has to do with user interaction, or running under vnc, or ....?
