-- Information about the crash:
- What I was doing when the application crashed: Asked by krop that I should remove my old Event from Traditionnal calendar. I've added my .ics file as an ical ressource.
Import process works.
Then I want to remove the old one. at that time akonadiconsole crash, virtuoso-t was running at 100% ...

The crash can be reproduced some of the time.

-- Backtrace:
Application: Akonadi Agent (akonadi_nepomuk_calendar_feeder), signal: Segmentation fault
