Humm, context==0 doesn't make any sense.  That may be a compiler optimization sideeffect though.  No idea.  Any more detail?  Which font was involved, etc?

Comment 2 Pedro Villavicencio 2009-10-26 18:25:06 UTC

seems that it was caused by /usr/share/fonts/truetype/ttf-dejavu/DejaVuSansMono-Bold.ttf font, i'm asking for extra details
