Application: korganizer (4.4.10)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
I removed and re-added some remote calendars (some https-URLs of Horde/kronolith) which somehow were not been reloaded any more.

While re-adding the remote calendars, I pasted the string "remote-Calendar" by accident to the download URL. I don't know if this is connected to the incident. I fixed the URL, however I still get errors:

Prozess kann nicht gestartet werden: Aufruf des Ein-/Ausgabemoduls nicht möglich.
klauncher meldet: Unbekanntes Protokoll „“.
(German message - my translation:
Process could not be started: Call of an I/O module not possible.
klauncher message: unknown protocol "".)

The error is displayed like every 5 minutes (probably when the calendar is reloaded), after some time and working with korganizer, it crashes.

The crash can be reproduced some of the time.
