Version:           4.2.1 (using 4.2.1 (KDE 4.2.1) "release 104", KDE:KDE4:Factory:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (x86_64) release 2.6.27.19-3.2-default

Opening an ICAL file from Krusader by pressing F3 results in a crash.
Krusader uses a KOrganizerPart to view ICAL files.
I will attach the problematic ICAL file for reproducing.

Backtrace:

Application: Krusader (krusader), signal SIGSEGV
