This line only happens when pulse receives an "InterfacesRemoved"
message from Bluez. Whatever is going wrong in your system, it's
happening in the bluetooth stack itself. Pulse has no control over it.
I think you'll need to ask for help from the Bluez project.

No, /card_2 is a reference to the transport path from the bluetooth
stack. Nothing to do with the card numberings in pulse.
