Thanks for the easily reproducible test-case.  The problem was that
`set-window-parameter' rejected invalid window arguments but
`set-window-configuration' called it with a not yet valid window as
argument.  I now restored the Emacs 24.1 behavior which allows any
window as argument.  Please try again.

Thanks again, martin
