Adding a record to a list feed adds a row to the worksheet, skipping empty rows

[Sagi Smolarski]

Per the documentation, adding a new record is supposed to add it at the 
first empty line in the worksheet.
What I am seeing is that regardless of empty rows available at the bottom 
of the worksheet, a new row is created and the record is saved in that new 
row.
Ugly...

This is the gist of what I'm doing to add a record (python):

        cl = gdata.spreadsheets.client.SpreadsheetsClient()
        new_feed = gdata.spreadsheets.data.ListEntry()
        new_feed.set_value("col1", "blah")
        ...
        ret = cl.AddListEntry(new_feed, spreadsheet_key, worksheet_id, 
auth_token)

Any ideas on how to actually add it on the first empty row?

I didn't get any answer on my previous post on this forum, but I'm not 
losing hope yet... (Vic?)
