Firefox gives confusing dialog if tokens expired

[geofft]

I just unlocked the screensaver on a Lucid machine that I'd been logged into for a while (and on which tokens expired), and running firefox gave

(firefox-bin:9717): GnomeUI-WARNING **: While connecting to session manager:
None of the authentication protocols specified are supported.

(firefox-bin:9717): GnomeUI-WARNING **: While connecting to session manager:

/afs/athena.mit.edu/user/g/e/geofft/.esd_auth: Permission denied

and I get a profile manager dialog box with no profiles listed.

It would be nice if, say, firefox-wrapper gave me a dialog box telling me I should renew, and errored out. (This also seems like a change of behavior in Lucid?)
