It definitely is. I just replied to that, but the precise problem we're 
having was reported upstream as #279665: 
https://bugs.kde.org/show_bug.cgi?id=279665
However, I do not think this is actually an upstream bug. I believe this 
is simply an incompatibility between KOrganizer 4.4 and (some part of) 
KDE 4.7, although I can't say what it is exactly for now.
