OK, apparently it's broken by default since you all have this problem.
I think I just have some settings on my system that make it work
properly.  For example, I start X server with all font paths that I
need (I don't use SLIM), not sure if it relates.

"xset -q" gives me:

...
Font Path:
  
<profile>truetype,<profile>X11/misc,<profile>X11/100dpi,<profile>X11/75dpi,built-ins

where <profile> is my guix profile with fonts.

Also I don't use 'font-alias' package, instead I use a "pure"
modification of it as described at
<https://lists.gnu.org/archive/html/bug-guix/2015-12/msg00022.html>.

But, well, I have no idea why xterm menus work for me :-)
