backref and multibib

[zazarara]

Hy,

It seems there is a little bug when using backref package and multibib.
The second bibliography created with \newcite has the line
@WriteFile{brf}{\backcite{RAB_CMAME07}{{1}{(document)}{Doc-Start}}}
in the .aux file.
Unfortunately the .brf file is not created.
If I manually create the brf file for this second bibliography, the page backreferences work...

Find enclosed a minimal working example.
Thank you very much for your help.

This here is the wrong repository. backref is part of hyperref. So I'm closing here.
