Comment #28 on issue 2990 by address@hidden: \RemoveEmptyStaves in StaffGroup  
context crashes
http://code.google.com/p/lilypond/issues/detail?id=2990

The patch presented in comment #24 is pretty artless and tailored to this  
particular report.  Even if we get to agreement about how (and where and  
whether) to deal with a generic recursive condition like in Mike's patch,  
the error situation for which _this_ issue has been created seems likely  
enough to trigger that a less generic error message makes sense.

If there is sufficient agreement that it makes sense to use _this_ issue  
for the \RemoveEmptyStaves deal only, I can put the patch on Rietveld and  
Mike would open a separate issue for the general "recursive structures"  
check.
