[plugin FeedWordPress] Bug: double update for updated feeds

I feel like the boy who cried wolf wolf. I hope this time I am in the right.

I turned debugging mode on, on the FeedWordPress plugin, and found out something interesting:

I had a feed which had an updated post in it. The result of the FeedWordPress was to update that feed twice, at least that’s what the debug output shows.

Here is the output:

Update complete. 0 new posts were syndicated and 1 existing posts were updated

Also, another interesting thing is that I changed the site wide setting to not update posts which where updated, but it still updated it. I then looked and found that for this feed there was an override that said to update that feed even if the site-wide update feature said not to update it.
So the bug might have something to do with that (or there is a bug in the debugging output).

I would be glad to know if this turns out to be true.
