The code uses imagemagick "convert" to determine the width in pixels,
which is font dependent. So I assume something broke on the system -
update of the system package, or maybe imagemagick or the font was
removed. This part of the code is not exactly robust unfortunately - if
I recall correctly, you even had to install a few missing packages to
get this to work after I implemented the badges.
