 Replying to [comment:6 deryni]:
 > Unfortunately there isn't much pidgin can do about this at the moment as
 it really does need to keep the local copy and there is no extant XMPP
 provision for this. There was recent discussion on some of the XMPP lists
 about roster version sequencing that would allow for better client-caching
 semantics (for bandwidth limited clients) that would have the nice added
 effect of making this sort of situation not a problem. I'm hoping that
 actually goes somewhere, I may actually poke them about it again and see
 what the story is.

 [http://xmpp.org/extensions/xep-0237.html Roster versioning] support will
 be in the next release (likely 2.6.5) barring any emergency releases,
 though libpurple still does not notice deleted roster entries if the
 server does not support versioning.
