Version:           unspecified (using KDE 4.7.3) 
OS:                Linux

Trying to access a remote iCal-calendar crashes plasma-desktop. Desktop keeps
crashing until akonadi gives up. After that it is possible to restart
plasma-desktop from the command line. It is also then possible to actually look
at the calendar entries in kontact. The added ical is disabled in korganizer,
but it can be switched on, and the entries will show up normally. However,
right-clicking the akonadi_ical_resource_N and selecting "update calendar
folder" reliably crashes the desktop.

This is kubuntu 11.10 using KDE 4.7.3

The remote ical-calendar worked fine earlier. It is read only. The crash
happens also at least in kde 4.7.2. I have only access to one remote
ical-resource, which is in google. Therefore I cannot test other calendars, but
I'll be happy to test some others if there are any available for testing. 

Reproducible: Always

Steps to Reproduce:
0. Start akonadi. Resources come up fine, if there is no remote iCal
configured.
1. Add a remote ical-resource to akonadi (ICal calendar file).
2. Press OK
3. Observe the desktop crashing a few times, until akonadi gives up on trying
to handle the ical resource


Actual Results:  
Actually, plasma-desktop sefaults:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault

Expected Results:  
I expected the desktop not to crash. Actually it was somewhat akward as the
first thing after upgrading to kubuntu 11.10 was the desktop crashing
repeatedly.

Calendar resources keep flickering in korganizer as akonadi tries to handle the
ical resource. If I try to kill manually the agent launcher
(/usr/bin/akonadi_agent_launcher akonadi_ical_resource akonadi_ical_resource_N)
it will emerge immediately with another PID.

Starting korganizer from a command line gives this a few (20 or so) times:
korganizer(21354)/libakonadi
Akonadi::MonitorPrivate::slotStatisticsChangedFinished: Error on fetching
collection statistics:  "No status for this folder" 

I attach two plasma-desktop outputs and backtraces, that I managed to get. I am
not sure if this is a bug in akonadi or in plasma-desktop. Apparently desktop
tries to  access the calendar also. I have "Digital clock" applet in the panel.
It shows the calendar entries in its pop-up calendar.
