saving custom search as smart group produces back trace

I took the following steps on demo.civicrm.org:

Clicked Search -> Custom Searches

Clicked "Find Contribution Amounts by Tag"

Selected Date range: 10/10/2011 - 10/10/2012 (did not select a tag)

Clicked Search

One result found. Selected "New Smart Group" from actions

Created a name for the new smart group (did not check email)

Clicked "Save Smart Group"

And I got this backtrace:
