Maybe there _was_ a bug.

I have interfaces that start with a "c" and that alphabetically comes
before "ethX" or "pXpY".
I haven't seen any problems with this configuration.

I don't have an IP address (and gateway+dns info) on my bridges.

This "bug" you speak of may be entirely related to your Ethernet bonding
though and not the bridging aspect.

Thanks for sharing configs.
It's always helpful to see how others are configuring their systems.
