Version: (using KDE 4.1.96) Installed from: Ubuntu Packages I can reproduce quite easily this crash: Put quite some files in the trash bin so that it span over several days/mounth. open the trash bin, and open the "today" tab for example but don't select a file or a set of files. Go back to the trash bin folder icon and ask to "empty recycle bin". When I do this I get kontact log: Calling appendChild() on a null node does nothing.

I also get this back trace (which is said to be not very usefull in french). Cette pile des appels apparaît être inutilisable.

As you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks :)
Here is a more usefull backtrace hopefully.
