Maybe the newest versions of MinePeon are somehow incompatible with bfgminer.
I will check into this when I get home, it would be a bit of a bummer if it is true. The only reason I have been able to support both bfgminer and cgminer is because the API is the same and if they start to differ there is going to be problems.

I wrote the API and as with a lot of cgminer he copies copious amounts of our cgminer code changes into his releases.
We don't copy stuff from his downstream.
Every single major argument he had with me regarding design, when we were both working on cgminer, he has implemented it how I said.
The last major change I copied from him was the ModMinerQuad code.
It didn't work, so I rewrote it all when I finally got an MMQ (even though he was paid by Tom to submit the changes to cgminer, since we couldn't test them we just accepted the changes ... that didn't work)
He has sent pull quests that clearly would cause problems.
So we take little notice of any downstream changes he does.
