Louis,
this has been fixed in 2.8.2-svn-14:
2009-03-19 Andrew Jaquith <ajaquith AT apache DOT org>
* 2.8.2-svn-14
* Fixed bug in XMLUserDatabase that was preventing UIDs from being
saved, which generated tons of NPEs afterwards. Added unit tests
to check for correct saving of UIDs. Tightened input filtering on
user profile fields to prohibit more characters.
