- Does it crashes again if you repeat the steps you described ?
Thanks

Comment 2 Nick Stallman 2009-09-04 01:12:09 UTC

Unfortunately it didnt crash when I did it again.

The only thing I can think of is I wasnt dragging as fast.
I was dragging a box around all of them, and then scrolling quickly down the list.

Comment 3 Peter Penz 2009-12-18 18:59:57 UTC

Thanks for the report. I've set this issue to RESOLVED because of the massive Nepomuk changes done in KDE SC 4.4.0 (I cannot reproduce the issue). Please reopen the report if a similar crash occurs with KDE SC 4.4.0.
