Bug 224777

Version:           Kontact 4.4 rc2 (using Devel)
OS:                Linux
Installed from:    Compiled sources

When entering a new event in the Kontact and the sub-dialog with multiple folders is shown, clicking the "create new event" OK button crashes the application.

I will atach a screencast of the situation.

Here is the backtrace : 

Application: Kontact (kontact), signal: Segmentation fault
