I installed the following debugging

diff --git a/src/gtkutil.c b/src/gtkutil.c
index c4d2ef9d80..b1b3e4c397 100644
--- a/src/gtkutil.c

and tried using the gtk selector (via M-x menu-set-font).  I only have
one font installed that has both normal and medium variations "Nimbus
no9", so I tried that.  And I got:

Weight: 400, symbol normal
Weight: 700, symbol bold

And, yes, the thing that's called Nimbus No9 Medium does look like a
bold in both the gtk selector and in Emacs.  So I don't think I have a
proper font to experiment with...  does anybody know of a font in Debian
Stable that has both varieties?  SauceCodePro was the example in the
bug report, but that does not seem to be available here.
