nautilus crashed with SIGSEGV in gconf_client_remove_dir()

[ingo]

Binary package hint: nautilus

Hardy amd64
I did following:
decrypted a pgp-encrypted text file via RMB (Seahorse?)
deleted the decrypted file using 'wipe-selected' extension of Nautilus.
cleared the (left over) applet in the GNOME-panel (keeping key is disabled in Seahorse settings)
logged out from gdm (GNOME-session)

Logged in on the virtual terminal #1 (Alt+F1) and found the file /var/crash/_usr_bin_nautilus.1000.crash
On logging in to gdm again, I found the pop-up of apport, creating this report.

Also ~/.xsession-errors contains a lot of warnings, see here:
