Look through GAL where? In the Contacts app or auto-completing in the recipient entry fields?
And those unwanted "things" are -- I assume -- are showing as "human name" or the found entries?
E.g.:
----
sip:blah X400/CN/O=foo
foo@bar.com
---
John Smith
john@smith.com
---
that sort of thing?
The "human name" values were not showing at all prior to this build (in GAL search results).
But using sip or X400/500 addresses as "human name"-s isn't exactly right either.
Debug log please, with "raw session data", you can send it to kmansoft / gmail and I'll look at it today.
