This bug has been fixed.

commit 6407d74c5106bb362b4087693688afd34942b094
Author: Alexander Holler <holler@ahsoftware•de>
Date:   Tue Jun 7 00:51:35 2011 -0700

    bridge: provide a cow_metrics method for fake_ops
    
    Like in commit 0972ddb237 (provide cow_metrics() methods to blackhole
    dst_ops), we must provide a cow_metrics for bridges fake_dst_ops as
    well.
    
    This fixes a regression coming from commits 62fa8a846d7d (net: Implement
    read-only protection and COW'ing of metrics.) and 33eb9873a28 (bridge:
    initialize fake_rtable metrics)
    
    ip link set mybridge mtu 1234
