Description

Under certain circumstances, calls to UserManager.getUserDatabase() are made before the user database is actually initialized, resulting in NPEs. To resolve, we simply need to replace internal references to m_userDatabase with getUserDatabase(), which will lazily initialize the database if it has not already happened.

Not sure why we didn't spot this before, but it bit me in the a** yesterday.
