-- Information about the crash:
sometimes when clicking the little bell notifications icon to see recent notifications causes plasma to crash

the crash happens when clicking the icon, the UI never shows up

it's inconsistent, haven't figured out any pattern for when it does/doesn't happen

The crash can be reproduced sometimes.
