Please unblock package cairo
It fixes several important bugs which could lead to crashes (in evince)
or broken print output. We have a large number of duplicates, so it
seems worthwile getting those fixes into wheezy.
Changelog:

+Subject: polygon-reduce: Reduce broken stopped-edge continuation
+
+This is hopefully a lesser used path and the attempted optimisation to
+continue a stopped edge with a colinear stopped edge highly unlikely and
+lost in the noise of the general inefficiency of the routine. As it was
+broken, rather than attempt to rectify the "optimisation" remove it.
