This report should be moved to dolphin. It doesn't belong to nepomuk.

The backtrace of the crash does not contain any Dolphin specific code and is related to Nepomuk. In KDE 4.7 Dolphin will not crash anymore on such kind of issues however I think it is useful if the Nepomuk team has a short look to the backtrace to check whether the issue might be related to Nepomuk itself or a wrong usage of Nepomuk (my current guess is that the issue might be a thread-safety issue - as in 4.7 those things are executed in a custom process this might be "solved").

My mistake. I didn't look probably into the backtrace. I'm sorry.
