CHIRP

After displaying the Banks(Band A) tab, I select File --> Export. I receive the following error on the screen:
There was an error during export: 'MappingMembershipEditor' object has no attribute 'prefill'

I see the following error on the console where I started Chirp:
ERROR: -- Exception: --
ERROR: Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/chirp/ui/editorset.py", line 363, in do_export
dst_rthread)

gobject.idle_add(current_editor.prefill)
AttributeError: 'MappingMembershipEditor' object has no attribute 'prefill'

ERROR: ----------------

I assume that the Chirp Export function will allow a different file export format when different tabs are in focus so as that a user can make changes offline (sort-to-speak) and then import those changes. If not, then perhaps this is a symptom of the previous defect I raised moments ago about the error when displaying the Banks(Band A) tab.
