Comment 1 Frank Reininghaus 2011-02-06 20:14:15 UTC

Thanks for the bug report! This seems to be related to Nepomuk. Looks similar
to bug 249186, but that is supposed to be fixed in 4.6.0. A similar report for
4.6.0 is bug 265609.

Comment 2 Christian (Fuchs) 2011-02-06 20:17:07 UTC

Hi, thanks for the quick response, as I am using 4.6 this is probably not the bug that got fixed in 4.6. 

It might be related to the other one, but as said, it seems to happen with not only pdf but audio-, video and other files as well. 

It seems to me that it only happens with tooltips enabled, though. Due to exams I currently don't have much time to investigate, but I reported anyway since Dr. Konqi popped up. 

Kind regards

Fixed in current master (4.7)

Thanks for the good work, this really was an issue.

Kind regards, 

Christian
