So now it looks like the default font displays fine, but your system has
problems displaying the bold font.  That is a slightly different symptom
from what you had before.  Please show the output of C-u C-x = for the
`bold' and `mode-line-buffer-id' faces.  You can do this by typing
M-x describe-face- RET bold RET, moving the cursor to the text that says
"sample", and typing C-u C-x =.  Similarly for `mode-line-buffer-id'.
I'm only interested in the part that reports the font.  For sample, on
my machine it says

              display: by this font (glyph code)
    xft:-unknown-Droid Sans Mono-normal-normal-normal-*-13-*-*-*-m-0-iso10646-1 
(#x56)

One possibility is that you have installed a buggy font which does not
include bold glyphs.
