--- Comment #2 from A. Wilcox (awilfox) <awil...@adelielinux.org> ---
We were still using 5.9.6 when this started, but we have since updated to 5.9.7
with no change.
Valgrind output is not helpful:

I really hope this does not turn into another round of hot potato where the KDE

decks or backgrounds in KPat.
I will attempt to bisect this crash and see if I can find an exact commit that
causes it.
