anyone know if there is a problem putting a gfci receptacle on a arc fault protected branch circuit?

I do not think it would pose a problem.

Check out the link and scroll down to
"Will an AFCI trip when testing a GFCI receptacle installed on the same circuit?"

Thanks for the link. It is not something I have done in the past, but I had some AFCI circuits that were lightly loaded, and decided to throw the ensuite on with them.
