Where is this function declared? What kind of exception is raised? C has 
no exceptions, and C++ exception needs a different form of declaration: 
*http://docs.cython.org/docs/pyrex_differences.html#c-exception-handling*

The "except NULL" is for propagating within-Cython exceptions, see 
http://docs.cython.org/docs/language_basics.html#error-return-values

Is this the reason for your problem? I might be missing the mark here.
