Notices when editing and saving price set field which has price value options

Edit and save price field of type radio (i.e. price field has price field value rows associated with it) gives this notice multiple times:

Notice: Undefined index: option_label in CRM_Price_BAO_Field::create() (line 126 of /Users/dgg/svn/crm_v4.2/CRM/Price/BAO/Field.php).

To recreate:

• New price set for events
• Add price field - type = radio button. Define 2 options on the add form.
• Save
• Now edit that same price field, and click Save

(Moved this issue from my comments in 10117. Confirmed that it is still a problem as of today's svn commits.)
