I briefly tested that:
* Now there isn't an infinite loop
* BOSH clients (Gajim and Oneteam) can login correctly as usual

The patch is committed in 2.1.x branch.

Ok. If you take a look and find any problem in the patch, or
have an alternative/cleaner solution to the loop problem, please comment it.
