Version:           1.1 (using 4.1.96 (KDE 4.1.96 (KDE 4.2 RC1)), Project Neon)
Compiler:          cc
OS:                Linux (i686) release 2.6.28

Every time I click on a to-do list item in summary, kontact crashes completely.

Way to reproduce:

1. create todo item
2. edit options of summary and enable to-do list
3. go on summary page click on todo item and it crashes

Thanks for the help.
