Please, please, always copy-and-paste the traceback when reporting an
error. I know you aren't formally reporting a bug here, but it always

Cython/Pyrex code does a runtime check on the struct sizes of types.
We have carefully added a member to the PyArrayDescr struct; i.e. it
shouldn't cause any actual problems, but Cython does the check
anyways. This affects a few modules in scipy, but shouldn't have
affected anything in matplotlib. The traceback may help us identify
the issue you are seeing.
