Application: keditbookmarks (4.4.2 (KDE 4.4.2))
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-19-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
In Beta-1 of Kubuntu 10.04 LucidLynx (Linux 2.6.32-19-generic #28-Ubuntu SMP Wed Mar 31 17:46:20 UTC 2010 i686 GNU/Linux) I was organizing bookmarks in Konqueror using the default tool.  I dragged some bookmarks into a bookmark folder and my bookmarks "disappeared".  No panic, I clicked the "undo" icon and the crash assistant dutifully appeared.  :-)
