The Ambiguously Overloaded Operator

It's been a while since we've had a good CGAL error. Went to upgrade to CGAL 4.5.2 and got this:
/Volumes/RAID/code/xptools/src/XESCore/MapPolygon.cpp:22:0 /Volumes/RAID/code/xptools/src/XESCore/MapPolygon.cpp:22: error: ambiguous overload for 'operator+=' in '* extent += ((const CGAL::Point_2 >

I am pretty sure the actual problem is trivial and obvious, but it'll be easier to fix if I ignore the error message.
