As I also am being affected by this, maybe I can give some extra info.
The file /etc/X11/rgb.txt used to be installed as part of x11-common (and still is for Debian unstable).
Recent versions no longer include the file, but still install a (broken) symlink to it
See /usr/share/doc/x11-common/changelog.gz:
xorg (1:7.4~1) experimental; urgency=low
[ Julien Cristau ]
* X.Org 7.4 release candidate
...
* xserver 1.5 doesn't use an external rgb database, don't bother installing
Unfortunately, it's not only xserver that is affected by this file. Its lack breaks netpbm, xcolors, vncserver, and so on.
