Ok, on the faulty system it is indeed Bitstream Vera Sans. On the other 
(working) system it is Arial. However, I changed the toy text API font 
to a serif one using cairo_select_font_face() and the problem persists.

That would be nice. I have attached the TTF font files to this mail, 
along with a valgrind output of a typical session which seems to 
indicate problems with uninitialised values in conjunction with text 
handling. Maybe that could help you.
