Timeout not being validated

I did a commerce kickstart installation with some default product and then installed this module.
Then I set the "Product display" as "Auction display content"

Then I tried to place a bid on an already existing product and I got this error:
PDOException: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'auction_timeout_timeout' cannot be null: INSERT INTO {field_data_auction_timeout} (entity_type, entity_id, revision_id, bundle, delta, language, auction_timeout_timeout) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6); Array ( [:db_insert_placeholder_0] => node [:db_insert_placeholder_1] => 2 [:db_insert_placeholder_2] => 2 [:db_insert_placeholder_3] => product_display [:db_insert_placeholder_4] => 0 [:db_insert_placeholder_5] => und [:db_insert_placeholder_6] => ) in field_sql_storage_field_storage_write() (line 448 of /home/xpete/public_html/commerce/modules/field/modules/field_sql_storage/field_sql_storage.module).

This happened because the timeout value was empty so I edited the product and set some timeout value and fixed the problem.
It's not exactly a a bug on this module but I think the module should do some validation on the timeout while placing a bid to make sure the timeout is not empty and haven't been exceeded.
