Bug 290572

Application: keditbookmarks (4.7.4 (4.7.4))
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
whilst rearranging my small number of bookmarks and folders, I tried to drag one to the end of the list, after the last existing folder.  It did not go there but popped up to the top of the list.  i dragged it back down to the end again and kbookmarkeditor crashed.

I tried to recreate but could not, but it seems anyway to be impossible to drag a folder to the end of the list, the insertion bar never gets there.  It stops at the end of the previous folder.  Presume this is something to do with why it crashed.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Bookmark Editor (keditbookmarks), signal: Segmentation fault
