[Babel-users] Possible crash in Babel 0.91

[Juliusz Chroboczek]

There's a possible crash in 0.91, which I've discovered Friday last but
didn't have time to announce.  An invariant is violated when an interface
goes down, which may cause a crash when it goes up again.

The patch is attached, it's also in the Darcs repository.  I'll release
a fixed 0.92 when I have some time.
