Differences between normal and grey case are:

   -    Foreground: unspecified-fg
   -    Background: unspecified-bg
   +    Foreground: black
   +    Background: white

   -          Font: unspecified
   -       Fontset: nil
   +          Font: #<font-spec nil nil nil nil nil nil nil nil nil nil nil nil 
((user-spec . monospace-12))>
   +       Fontset: -unknown-DejaVu Sans 
Mono-normal-normal-normal-*-13-*-*-*-m-0-fontset-startup

I had hoped that the bisecting could be avoided, but here we go.

The "grey background" started with revision 99013 (and reverting this
changeset in the trunk of today brings back the old behaviour):

   revno: 99013
   committer: Dan Nicolaescu <address@hidden>
   branch nick: trunk
   timestamp: Mon 2009-12-07 06:30:30 +0000
   message:
     Get the background mode from the terminal for xterm, and set
     faces accordingly.
     * term/xterm.el (xterm-set-background-mode): New function.
     (terminal-init-xterm): Use it in case xterm supports background
     color queries.  Recompute faces after getting the background
     color.

BTW, I use xterm version 250, in case that it matters.
