When starting Emacs with X11 (fetched a 1-2 hours ago, i.e. after
the unicode merge), I get the error:

As you can see, "xrdb" doesn't report anything.  But i found out that
the culprit is the file /usr/share/X11/app-defaults/Emacs (attached to
this message [1]).  After moving away this file, or with "-nw", Emacs
runs as excpected.

I don't know what the problem is with this app-defaults/Emacs file,
but Emacs should handle it more gracefully.

Bye, Reiner.

[1] The app-defaults/Emacs file is from the Emacs 22 package
    (emacs-x11-22.1-23).   I'm running openSUSE 10.2, but IIRC this
    package is from openSUSE 10.3.
