Comment 1 Chris Wilson 2013-01-11 09:07:49 UTC 
Can you attach the chromium-tabs.trace triggering the error? Then do a 'make clean && make' in your traces directory after installing the updated cairo.

Yes, please find the attachment. The issue still exists after 'make clean && make'. The cairo-trace commit is cdb266e660743e680314ef4b0c4655a311f32ca4.
