It's Ok to have both a KeySource and MasterSource.

It's rare that it would make sense to do so and as such this could be a
cause for trouble in an application. If this does eliminate the error
message I would like to know about it.

One thing I pride myself on is while IBO being feature rich, the features
all get along together harmoneously.
