well, i can definitely reproduce this, that was not fun. https://bugs.launchpad.net/ubuntu/+source/cairo/+bug/1476736 this seems related. It appears to be any bitmap font not just terminus. The checks were introduced in cairo with this commit: http://cgit.freedesktop.org/cairo/commit/src/cairo-scaled-font.c?id=b5dcc8ce4450de1e48fd0586fddb5ed658719b28 I have x11-libs/cairo-1.14.2 installed. Adding the x11 team since this seems more like a cairo problem.
Since we're 4~5 years past this bug being confirmed without any new sightings I'm going to speculatively mark as OBSOLETE. If anyone can reproduce the issue today, please reopen.
