In our environment we have two themes

1. Log in theme
2. All Space Layout

I want to use #2 for all spaces except for the log in page and the dashboard.  When I go into the theme administration under the Manage Spaces tab this is what it looks like:
 
 
Then I change all of the spaces to have the "All Space Layout" and it looks like this and I get this error message:
 

 
I can click ok on the error message but when I refresh this screen or navigate away from it the spaces are all messed up.  Here is what it looks like when I come back to this page:
 

 
I have tried this on IE6, IE7, and Firefox 3 with no success.  I have no idea what that blank error message means.  Please help.
