Error in 3.4.1

Hi,

One of my users is reporting an error occurring and it appears to just
be a typing issue that is untrapped.

1. Save Changes on the Jumbo tab gives the following error.  Submitted a
syntax error to the ticket number quoted for the Depends on Field.  Had 
typed in #4 instead of just 4. 

*System error*

*error:*        Can't call method "Scheme" on an undefined value at
