When deleting the last device (an effects pedal, for example) in a chain that returns to the same device (as in an send/return chain on a mixer) a connection will be left that connects the output to the input of the same device, creating a feedback loop. I'd expect the input/output connectors to be left open, like in Flash.

Steps to reproduce this bug:

1. Get any mixer with send/return connectors (Centroid or Minimixer)

2. Create a chain of one or more devices connected to the send and return connectors of the mixer.

3. Delete the devices forming the chain.

4. When the last device of the chain is deleted, a loop connection is left that connects the mixer's send straight into its return.
