I think Plasma's configuration was reloading due to a change in the system settings - I was playing with stuff to try to figure out a problem report, but I don't remember what I changed that caused the crash.

Ok, thanks. Unfortunately that makes it a lot less likely that we'll be able to figure out what caused this. If you can manage to reproduce the issue with the same backtrace again, and you remember what you did, feel free to re-open the bug report. Thanks for understanding!

Found a generic duplicate for it, actually.
