[SciPy-User] Gaussian filter on an angle

I'm trying to blur an angle field, but it's not easy ;)
Applying gaussian_filter (from ndimage) on the sinus and the cos is
not enough to have a smooth angle field, and of course applying
gaussian_filter directly on the angle field does not yeild
satisfactiry results.
Does anyone know of a function (even if it not in Python yet) that
could gaussian filter an angle field? Something like a Riemanian
filter (instead of an Euclidian one)...
