Bug 254554

Application: kontact (4.4.6)
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
I created a few new filters, clicked ok to go back to the make application.  I selected one of my newly created filters and it crashed.  When it came back up, all of the new filters were gone.  I had created a single filter a week prior and that one works and is still present.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
