maven site deployments with .. in paths fail

Since Nexus 2.11.1 I have a problem deploying sites of maven modules via dav protocol which have a parent and where I do not want the site to deployed at a path below the parent site.

Maven site plugin generates links relative to the site of the parent project. Nexus does not accept these relative links anymore.

See (the edited) log excerpt below for an example.

Do you have an idea what I can do other than requesting / implementing a change in the site plugin, changing my site deployment structure? I'd also rather not change the transport protocol (if that would be a solution) because that probably would be difficult to organize.
