[ckan-dev] problems upgrading to CKAN 2.2

[Ivan]

Hello,

I'm having similar issues as Hildegard when trying to reload db dump
from 2.1.1 into 2.2a or 2.3a (current master tip).


$ paster db clean -c $inif
$ paster db load  /tmp/20140210_ckan-db-dump.sql -c $inif
...
Loaded CKAN database: /tmp/20140210_ckan-db-dump.sql

AttributeError: 'NoneType' object has no attribute 'isoformat'


I can do `db load-only` and `db update` and get users and
organizations in the new instance, but 0 datasets.  `search-index
rebuild` fails with the same error message as above.

db version on "2.1.1 ckan instance" is 71.
ckan.plugins = stats text_preview recline_preview datastore (on both
2.1.1 and 2.3a)


Thanks in advance for any help and suggestions.
