Platform: Flatpak
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR

SUMMARY
I tried running the Flatpak nightly (master) build under Wayland and it would
crash after a few minutes of use.
STEPS TO REPRODUCE
1. flatpak run --command=sh --devel org.kde.skrooge
~/Documents/p/finance/pages.sk
2. Enter some transactions ("operations"). There may be a connection with
Skrooge's pop-up window containin matching text inputs.
OBSERVED RESULT
Four times in an hour, Skrooge crashed. I folllowed
https://docs.flatpak.org/en/latest/debugging.html to get a backtrace:
