Comment 1 Frank Reininghaus 2009-12-01 17:46:55 UTC

Thanks for the bug report! It looks like the file you've renamed was in KFilePreviewGenerator's list of recently modified files. The file item in this list became invalid after the rename, and accessing it caused a crash.

This is similar to bug 211525, but maybe not exactly a duplicate, because the item is renamed and not removed in your case. Maybe we also have to listen to KDirModel's dataChanged(const QModelIndex&, const QModelIndex&) signal to fix this...

Comment 2 Rado 2009-12-01 18:06:22 UTC

Thanks for the quick response. Actually it was a directory and i believe that I have never accessed it since I installed the new OS (Fedora 12)...
