One should be enough. I've tried doing exactly what you're doing, but I cannot reproduce. And the backtraces don't help all that much. One thing you might try is to run update-mime-database on /usr/X11R6/share/gnome/mime, /usr/local/share/gnome/mime, /usr/local/share/mime, /usr/X11R6/share/mime, and see if it helps. > > Pressing enter enter before the dialog shows results in a different, > probably unrelated, crash.
