Unable to create new smart group from find contacts results using Safari (v 4.0.3) browser

When attempting to select "New Smart Group" from the results page of an advanced search using the Safari (v 4.0.3) web browser on OS X, you must first select contacts. When you click on the "All XX records" radio button, all the checkboxes for each contact are checked, but the "Selected records only" radio button is selected instead of the "All XX records" radio button. This appears to be ok since all the records are checked/selected, but when you click "Go" to create the new smart group you get the following error, "Please select all contacts for this action.To use the entire set of search results, click the 'all records' radio button.", and are consequently unable to create the smart group. Creating a smart group using Firefox (v3.0.11) on OS X works fine.
