You'll have to force both systems you want to clip into one long
system, either by preventing breaks or (if it's only two systems long,
like the example above) setting system-count = 1.

Remove the \header block.

I'm surprised nobody's reported this error before, but it's due to the
fact that a \header block (or top-level markup) is included in the
list of systems for clipping, but has no System grob.  I'll push a fix
for this soon (it'll probably miss the next development release, but
might make it into 2.12.3).

Thanks for the bug report,
