Seems you were at least partially right. I did some addition research and 
testcases follow.

Here we go: 
testcase1 - [1] - couldn't be any simpler - compiles just fine
testcase2 - [2] - putting foo in the blah namespace breaks - [3]
testcase3 - [4] - workaround for testcase2, notice that including the 
boost/python.hpp before the template definition or not putting the template 
in the boost namespace breaks it.

boost 1.33.1 and gcc 4.1.2.
