Version:           Unbekannt (using 4.1.3 (KDE 4.1.3) "release 4.9", openSUSE 11.1)
Compiler:          gcc
OS:                Linux (i686) release 2.6.27.7-9-default

When adding an entry to the "TODO" list in kontact, the application crashed. This error seems to be infrequent and is not readily reproducable.

I use a default resource where calendar (and hence todo) items are stored in a separate directory.

I attach a backtrace.
