Crash: Midi and Instrument_name_engraver in StaffGroup (was Re: TAB question -- frescobaldi tab support)

[Trevor Daniels]

This looks like a bug.  An attempt to add the 
Instrument_name_engraver to a StaffGroup context *and* produce MIDI 
output causes a Crash under Vista.  Doing either separately is fine. 
Here's a minimal example:

\version "2.12.2"
\score {
 \new StaffGroup \with { \consists Instrument_name_engraver }
 a'
 \midi { }
}
