-- Information about the crash:
I added an iCal file based resource using the Akondai KCM (and gave it a filename that did not exist in a folder that did exist) and got the following crash report.

The other resources I have are Local Folders (offline) and Personal Contacts (has a green dot, but no status message, and I've just imported a bunch of contacts from a VCF file successfully).  The KCM also has a green dot (and no status message) for the iCal resource.  The iCal file seems to have been created successfully.

 -- Backtrace:
Application: Akonadi Resource (akonadi_ical_resource), signal: Segmentation fault
