I think that this isn't a bug. From the man pages of brconfig:

 Bridge devices create a logical link
 between two or more Ethernet interfaces or encapsulation interfaces  (see gif(4))

tun0 isn't a Ethernet interfaces. Anyway with OpenVPN you have to use
tap interface, instead of tun interface,to activate bridging.
tun interface is for routing only.
