Comment 1 Sergio Martins 2009-02-25 22:34:22 UTC
I can't reproduce this with KDE 4.2
Comment 2 Joao Candido 2009-06-15 15:20:50 UTC
I tried to create a new task, but the closed KOrganizer with SIGSEGV error signal 11. Attention, I'm using KDE 4.2.4.
Comment 3 Sergio Martins 2009-06-15 20:20:13 UTC
I can reproduce it now. I'll take a look at it.
