This sounds a lot like the symptoms described in https://athena10.mit.edu/trac/ticket/1162. This may be better in Quantal, but I haven't actually tested it. I can try to reproduce it, but unless there's some upstream fix, I'm not optimistic. I suspect the right answer here is to document disabling gnome-screensaver (or at least its locking features) and running something like Xscreensaver when locking is desired.
That having been said, the last time I tried to reproduce something like this, I couldn't (that is, I was unable to unlock successfully, long after tokens and even tickets had expired). As the login dialog is not actually appearing (if I'm reading this correctly), it may be a slightly different problem.
