Both ships explode upon attempting to dock

[Bandus]

I am attempting to dock two ship in space, each with a Clamp-O-Tron Docking Port Sr. I have tried docking twice now and each time the docking ports connect at around 0.1 - 0.2 m/s. Next, both ships explode...

I feel like I am well within safe docking speed. Am I missing something obvious?

The list of mods I am running can be found here. 

The vessel on the left is the one under active control, the one on the right is the target. Obviously, I line up the docking ports properly before moving in at 0.1 - 0.2 m/s. Screenshot is just attempting to show both docking surfaces. 

 

I will say (but I'm not sure) it "feels" like when the ports begin to connect the force suddenly picks up and the active ship almost..drives straight through the station. After the initial explosion both vessels take turn exploding and/or tumbling wildly and exploding.

Thanks!

They could be clipping through each other slightly at first contact. Because of this, when the collision physics kick in, they explode. I don't know how to fix that though. Sorry.
