Version:           4.1 rc1 (using 4.1.73 (KDE 4.1.72 (KDE 4.2 >= 20081112)) "release 3.1", KDE:KDE4:UNSTABLE:Desktop / openSUSE_Factory)
Compiler:          gcc
OS:                Linux (i686) release 2.6.27.5-2-pae

Testcase :

While doing tests, I created an event in korganizer and sent an invitation to one of my email addresses.

The crash occurs when I click on the answer notification email :

icalerror.c:104: BADARG: Bad argument to function
kmail: icalerror.c:106: icalerror_set_errno: Assertion `0' failed.
*** KMail got signal 6 (Crashing)
