Indeed, that worked, thanks (tho the performance wasn't noticeably
better).

I didn't need to do that for the font I use (running Debian, here).

It actually crashed with an assertion violation because a font `spec'
was nil where a vector was expected.  I used the quick-fix below which
appeared to work, but without knowing what it implies.  Can you take
a look and help me figure out what the right fix should be?
