I'm using python bulbs with Rexster and OrientDB. I'm trying to create an edge, but I get this error:
>> g.edges.create(g.V[0], "aoeu", g.V[1])
Traceback (most recent call last):

The funny thing is when I execute the command again, it works, BUT I get 2 edges created, which is WRONG.
On my Rexster server,
I get this error

What is the error I keep getting, and how do I fix it?

Fixed in OrientDB 1.7, see https://github.com/tinkerpop/rexster/issues/341 for more info.
