Description of problem:
Attempting to "Save & Recalculate" a newly created dynagroup from within the wizard appears to fail.  Furthermore, the dynagroup gets silently saved.

Version-Release number of selected component (if applicable):


How reproducible:
Everytime

Steps to Reproduce:
1.  Attempt to create a dynagroup.  give it a name of "foobar" and an expression of:

resource.type.plugin = Platforms
resource.type.name = Linux

2.  Click the Save & Recalculate button.  Note failure
3.  Click the Save button.  Note different failure.
  
Actual results:
* Save & Recalculate: User gets error, "Failed to Recalculate this group definition"
* Save:  User is given a fail notice that "A group definition with this name already exists"

Expected results:
Calc works
System should indicate that the dynagroup was already otherwise saved so s/he doesn't get stuck wondering what happened.
