corruption when saving score containing a system beginning with a start repeat on an mmrest
Ubuntu Studio 14.04, GIT commit: 3338af9
1) new score, 32 measure
2) add line break after bar 4
3) add start repeat to measure 5 (first measure of second system)
4) "M" to enable mmrests (you should have a 4-bar rest on first system, 28-bar rest on second system
Result: a bad-looking 28-bar rest on second system (it appears to be drawn twice):
Bad things then follow if you try editing, including crashes if linked parts are involved (eg, try adding a linked staff at this point).
