 On startup, Vidalia often complains that it could not authenticate to the
 user's X session manager:
 {{{
 Qt: Session management error: None of the authentication protocols
 specified are supported
 }}}

 Vidalia should not be attempting to connect to a session manager, and the
 fact that it does could leave traces on disk outside the TBB directory.

 It appears that Vidalia/Qt attempts to connect to a session manager iff
 the `SESSION_MANAGER` environment variable is set.  RelativeLink.sh should
 unset that variable.

 (Hopefully unsetting that variable will also keep Firefox from trying to
 talk to a session manager.)

 It appears that Vidalia/Qt will be unable to connect to the session
 manager even if it attempts to, because the user's `$HOME/.ICEauthority`
 file is not present in the TBB directory.  The GNOME 2 session manager did
 not log a message in `$HOME/.xsession-errors` when Vidalia failed to
 connect to it; hopefully other session managers won't log authentication
 errors either, but we shouldn't count on that.
