-- Information about the crash:
Hi there,

Was just messing around with the calendar applet settings. I don't know if it's related, but I switched on the "fr_fr" holidays calendar in the settings panel, hit "apply", then went in the calendar to see how holidays were displayed.
I didn't see anything and tried to go back and forth several months. Nothing changed display-wise.

I then clicked on the "calendar button" (come back to Today)...and it crashed !

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
