cron run causes feed:node to lose settings

Whenever the cron script runs:

- All the item nodes are updated
- The feed node is also updated
- The feed node has lost its taxonomy associations
- The item nodes do not inherit the taxonomy associations

So, I edit the feed node and reset the taxonomy correctly (and save it) Run the cron script again and it happens again: Taxonomies get lost from all items and the feed.

Also, if the feed node is promoted to the front page itself, then this setting is also lost and the feed node is "demoted" every time cron runs.
