Excuse me, I won't spam the discussion anymore :)
This is my last version of the workaround, this fixes both this bug and bug
#813373
The font developer team could fix the font hard-coded 'family', 'style'
and 'weight' properties easily to fix those bugs.

Ok, now this configuration works for 'Medium Italic' too (it was easier than I
thought).
Probably this is not a full range solution, but it surely fixed the problem
in my case.

Just following up on comment 42, I assume the equivalent to be done in
LibreOffice at convertWeight() in fontmanager.cxx:
Hold on, what I wrote above is for LibreOffice 3.7+/master, 3.6 still
guesses font weights from the strings in the GlobalFontInfo struct:
Also note that any nontrivial patch there will affect all fonts in
rendered documents opening us to a lot of havoc, if our vendor patch
makes documents being rendered different (different font weight might

was to drop 'Medium' and 'Medium Italic' (just) from the Ubuntu 11.04
