Comment(by cmbarton):

 The location wizard is a fancy wrapper for g.proj. It creates a proj4
 string and send it to g.proj.

 g.proj is supposed to return a datum transfer list when relevant for the
 proj4 string. This *USED* to happen with any relevant proj4 string. It
 seems now that it is ONLY happening when g.proj gets an EPSG code. The
 code to return the datum transfer seems to be working properly, since it
 works for EPSG. So my guess is that g.proj is no longer returning a datum
 transform list for proj4 strings.
