update28.py: TypeError: 'NoneType' object is unsubscriptable

Hi

As I mentioned in another message, I'm trying to deply dak.  After
switching to squeeze and getting update19.py to run, I'm getting the
following error:

$ ./dak.py update-db
Determining dak database revision ...
dak database schema at 27
dak version requires schema 31
updating database schema from 27 to 28

keep contents of binary packages in tables so we can generate
contents.gz files from dak

Any hints?

Best wishes.
