When trying to display a mail with an attached iCalendar event (google calendar invitation, or invitation send from kontact/korganizer), kontact krash.

The mail seems to be displyed just before the app crash.

I'm using archlinux, and recompiled the kdepim packages simplify modifying-it to include debugging informations.

Here is the backtrace I get:

Application: Kontact (kontact), signal SIGSEGV
