I have already reported the same:

It happens only with the Xft build, i.e. if you omit '--with-xft'
there is no such problem.
If you have the opportunity, please try the below patch, and tell me if the
problem goes away.
Stephen, does it really bring value to also accept XLFDs on the XFT build? I
get the feeling that using different X resources and separate face and font
handling function for the two builds would be cleaner and more usable.
lisp/ChangeLog addition:
2007-08-03 Aidan Kehoe <kehoea(a)parhasard.net>
* font.el (x-font-create-object):
When handed an XFT font name string, parse it as such.
* font.el (font-xft-font-regexp):
Don't check for the existence of xft-font-regexp; accept escaped
dashes and colons in font family names.

On the quay of the little Black Sea port, where the rescued pair came once
more into contact with civilization, Dobrinton was bitten by a dog which was
assumed to be mad, though it may only have been indiscriminating. (Saki)
