Could be related to the new DBusMenu stuff. (dbusmenu stuff shows up in the backtrace.

Unfortunately, I can't reproduce the bug and the Nepomuk code where it crashes does not exist anymore. Can you still reproduce it with Lucid?

I've tried it again since some of the new updates and it hasn't happened again since. Not sure if this means it was a one off or that it has been fixed.

It probably has been fixed, then.
