I tried it under linux (ubuntu) with 2.16.2 and 2.17.19. Your smaller snippet compiles without errors in both versions, but the InstrumentName does not appear, as you described it. Your whole score throws a lot of errors and warnings, shows the same lack of the InstrumentName, but it also compiles in the end (10min) and does not crash.
-> crash in 2.17.19 only under windows -> missing InstrumentName with grace notes in piano staff in all LP versions I hope this can help someone familiar with LP to trace down this bug.
