I don't know if that's still a problem, since the session manager/explorer
feature was added in the meantime, but I've tried to add guards to most
locations, except where it was obvious that getLastSession() must return
non-NULL because we already checked it before.

Should it ever actually be NULL, at least it shouldn't crash (at this point) any
longer, but I admit that I don't know how the client behaves when just returning
out of these functions without doing its work.
