I have to admit I'm stumped, but like I said I'm not a python expert.  I did 
a quick Google search and discovered that this has been seen before when 
using Boost.Python to wrap std::vector, *but only when using blender* see 
http://www.blender3d.com/forum/viewtopic.php?p=41828&highlight=&sid=c7039b55ca7fcb0c37584818cbb5cf66 
does this ring any bells?

Otherwise the only thing I can think of is maybe some kind of problem with 
modules getting unloaded in the wrong order, or maybe globals declared in 
your module getting destroyed after the std lib has been taken down.  But 
that *shouldn't* happen either.
