CLX vs. Ultrix

[Don Tillman <till@lucid.com>]

Apologies if this was already discussed, but could somebody clue me in
on the incompatibilities that the Ultrix X-server has with CLX?

Any call to QUERY-FONT (or anything that uses QUERY-FONT) blows out
during WAIT-FOR-REPLY with an:
  ">>Error: X-Error: Reply out of sequence 
   for display #<DISPLAY hostname 0>. "

This happens when the server is the microVax ([Ultrix-32 V3.0 (Rev 64)
UWS V2.0).  This happens when the client is either R2 or R3 CLX
running on either said microVax or a Sun.  

Anybody seen this before?
