Everytime I try to select a certain an edge on one of the objects in my scene, Maya gets a "fatal error" and closes.

Every other object works fine. It's just one which cause Maya to crash if I try selecting a loop.

This might be relevant:
I had a relatively flat object, which I duplicated and moved a bit to the left. I bridged faces from each object to the middle to connect them, and then combined the two.
I then merged the vertices to actually make it one object.

That leaves me with a loop down the center, which is the one I'm trying to delete.
