Saving score with some instruments suppressed and multimeasure rests messes up score
I create a score with two voices (soprano and bass). It has a block of measures where both voices rest. I choose to not display the soprano voice. I select option to create multimeasure rests. So far the score looks fine (see attached beforesave.pdf). Now if I save this file, close the score window, and re-open, the bass part is jumbled (attached aftersave.pdf). If I at this point ask for both soprano and bass lines to be visible, I see that both voices are jumbled, though in different ways.
Note if I save the mscz file without having first made a voice invisible, there is no problem.
I am attaching the mscz files before making soprano invisible and before multimeasure rests (test_multimeas_rest.mscz) and after doing these two steps (test_multimeas_rest_mm.mscz).
This all works fine in released MuseScore 1.3. Test results shown are with MuseScoreNightly-2014-07-16-2356-aaf966a, but I saw the same behavior in a nightly from 07-12, and I think also from 07-01.
