I cannot send mail with recent CVS.  When I send the message I get the
following backtrace.  I am using an Xemacs without mule.

Any ideas?

Signaling: (void-variable enable-multibyte-characters)
  message-send-mail(nil)
  message-send-via-mail(nil)
  message-send(nil)
  message-send-and-exit(nil)
  call-interactively(message-send-and-exit)

Following is the output from gnus-bug:
