I think you were bitten by an error that has been fixed in the latest trac release, but still exists in the production release. Take a look through the threads tagged 745:

https://bbpress.org/forums/tags/745

745 is the trac ticket where this was discussed. There are lots of workarounds listed in the forums and on trac.

Good luck.
