           Summary: Freezes when changing date of item in todo
           Product: kontact
           Version: 4.4.2
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: robert.wohlrab at gmx.de


Version:           4.4.2 (using KDE 4.4.2)
OS:                Linux
Installed from:    Debian testing/unstable Packages

Steps:
 * open kontact
 * open summary
 * open to-do list
 * change date of item (was 2010-05-07 and changed it to 2010-05-06)

When clicking on ok it will freeze the whole program. CPU idles.

I use akonadi to store my calender, but it seems to be independend on the
actual data storage in akonadi.

I did the same test again without using akonadi for calender data
(nearly empty ics file), but I couldn't reproduce it with it.
