The attached file crashes MuseScore
I thought this file was ok, I've added a layer but it does have a tag. I *thought* the file had loaded correctly a couple of times, I might be wrong however because it certainly doesn't now.
I'm looking into the layer issue, but I don't think it is part of this problem.
The program crashes after calling "tick()" on line 324 of rendermidi.cpp. The problem is that s2 is a null pointer at that stage. This occurs on the 28th call of collectMeasureEvents, tho' this is not the 28th time around that loop.
The program crash output is
Score::findSpanner(105): not found
Measure::read(): cannot find spanner 105
