Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "

This pattern repeats - there was at least 10000 entries in the backtrace.
Comment 1 Boris 2010-04-27 16:29:33 UTC 
I get this too.

$ korganizer --version
Qt: 4.6.2
KDE: 4.3.4 (KDE 4.3.4)
KOrganizer: 4.3.4
Comment 2 Sergio Martins 2010-06-20 16:40:32 UTC 
I saw this too but can't reproduce now, i think since i updated Qt.

can you try with a newer Qt and KDE?
