I did try that version. Bug still exists.
I think I know why you were unable to reproduce. It looks like the bug
only manifests itself when ip is working on an interface which has an
alias. That's what I get for writing a bug report at 2:30 am.
See attached file for debug output from Xen's network-bridge script.
The end of the output is where the script dies when 'ip addr flush'
throws the error.
