I found the bug: it's an infloop in update_text_area which can happen
when the pixel width of the current glyph is smaller than the lbearing
of the next glyph.  I'm not sure why the bug was triggered only under
the situation I described; maybe, only that exact geometry and font
produced the numbers leading to the infloop.

I've checked in a fix.
