[gaim-migrate @ 5682]
Fixed the bug where typing notifications (actually, any message where an
attribute was removed) would strlen() the value just freed. This was
causing the message size to be wrong on occasion (and probably very wrong
on other platforms), which MSN would then puke about and cause a disconnect
from the Switchboard server.
