The ctor looks like;
AttributeError (const std::string& reason)

but imho that can't be the issue since it works for all other cases where it's 
used. Or does it break also at the other lines if you just comment the 
207+etc. lines out?

hmmm... that sounds very wired.

nope. Also there are not templates used. May it be possible, that it's needed 
to explicit link against STL ?

It's just the error-string that is displayed.

Could this be another buildsystem-prob just like we had just some days ago 
with the -ldl / ${CMAKE_DL_LIBS} in python/CMakeLists.txt ? It may an idea to 
try to remove the additional ${CMAKE_DL_LIBS}...
