When I try to use nautilus to connect to a remove ssh server, it uses the gnome keyring stuff to store the password. The keyring app (is this seahorse?) pops up a dialog asking whether "/var/tmp/portage/.../nautilus (deleted)" should be allowed access to my password in the keyring. This is cosmetically bad because of the /var/tmp/portage stuff and the "(deleted)" part could scare a user into thinking something bad was happening. I also wonder if this could be exploited if another user were to create /var/tmp/portage/...blah.../nautilus and then ask it to get a password from my keyring. This dialog would then pop up on my screen and because I've gotten used to seeing this dialog when nautilus legitemately needs the password, I would likely click "allow".

I just tested this, and it said "/usr/bin/nautilus". I have 2.16.1. Can you re-test with 2.16.1?
Indeed it seems fixed (I'm having some trouble getting nautilus to forget the passwords long enough to reproduce that dialog but other similar dialogs don't have /var/tmp in them). Closing fixed, I'll reopen if I ever see it again.
