Unfortunately, the Novell plugin was donated by a corporate entity, is
no longer maintained, and none of the Pidgin developers have a server
to check it against.  We would happily accept patches to improve it
from a developer who does have access to a server.

There may be some level of defensive programming that can be performed
without a server, of course.  I haven't examined this code carefully
to see if, for example, simply aborting the operation leaves things
in a sane state.
