Comment 21 for bug 23917

Having the same problem here on Gutsy.
It started after installing Java 6 and the following applications that use Java:
-Truecrypt + tcgui

When trying to gksu nautilus, it does open the application but without rights and the following:

arno@arno-laptop:~$ gksu nautilus
Gtk-Message: Failed to load module "gnomebreakpad": cannot open shared object file: No such file or directory

(nautilus:8873): GnomeUI-WARNING **: While connecting to session manager:
