NPE in InitializerChecker when guest account is disabled

[Eli Doran]

I just setup Continuum and received a NullPointerException when trying 
to use disabled guest option. The problem is in 
org.apache.maven.continuum.web.action.InitializationChecker at line 
164.  I've included the neighboring lines below. The UserGroup is not 
checked whether it is null so the call "guestGroup.setPermissions(null)" 
causes the NPE. The same problem happens on my WinXP and Fedora Linux 
machines. Did I do something wrong? Am I missing something. All I had to 
do was check the guests box and it works fine.

Thank you,

       boolean guestAccountEnabled = getBooleanValue( map, 
"guestAccountEnabled" );

       if ( guestAccountEnabled )
       {
           configuration.setGuestAccountEnabled( guestAccountEnabled );
       }
       else
       {
           UserGroup guestGroup = store.getUserGroup( "guest" );

-->       guestGroup.setPermissions( null );  !!!! This causes the NPE !!!!

           store.updateUserGroup( guestGroup );
       }
