My rocket violently flips and rolls at distant orbit

[TheAngryHulk]

When I'm close to kerbin, my rocket is fine with EVA's. But when I go out too far (only tested at 6mil meters) the rocket violently flips and rolls when I do an EVA. It's done it twice now and I can't figure out why. Any help would be appreciated. I'm using betterburntime, StageRecovery and Kerbal Engineer.

So, when you are in LKO, you can EVA a kerbal, and everything is fine.  But when you are in a high orbit (>6000 km), EVA'ing a kerbal causes the ship to flip out?

If I'm reading that right, the only suggestion I have is to make sure SAS is off before EVA'ing. Try eva'ing in LKO, and high orbit with both SAS on and off, and see what happens. 

The mods you listed shouldn't have any affect like this.
