 -- You may want to have a look at the following related bug :

 sage: G= SymmetricGroup(5); x, y= G.gens()
 sage: A= GroupAlgebra(G)
 sage: A( A(x) )

 ...fails. This bug may or may not be automatically fixed by your patch.

 -- The docstring on line 367 of group_algebra.py mentions
 GroupAlgebra.__call__(), even though this method has been suppressed.
