Interesting, whole looking into bug #797471, I noticed the following:
$ for f in /usr/share/fonts/truetype/ubuntu-font-family/UbuntuBetaMono-*.ttf ; do basename $f | tr \\n \\t ; showttf $f | awk '/avgWidth/{print$1}' ; done | sort -t= -nk2 UbuntuBetaMono-BI.ttf avgWidth=499 UbuntuBetaMono-B.ttf avgWidth=500 UbuntuBetaMono-RI.ttf avgWidth=500 UbuntuBetaMono-R.ttf avgWidth=500
One of these, is not like the others.
