startStaff == -2probably causes this. How can astaffIdxbe-2??See https://github.com/musescore/MuseScore/pull/5488
staffIdx == -2turns out to be a result of incorrect handling of result ofSpanner::track2()function inundoAddElement().Fixed in branch master, commit 49fedc47c4
_fix #297428: crash on copying measure with slur and pasting it to TAB staff
1) Fix incorrect track2 assignment to spanners on pasting in some
situations due to not handling the case of track2 == -1.
2) Fix staff index checks in ScoreView code to avoid a crash if
incorrect staff index gets recorded to CmdState.
3) Add an assertion to catch invalid negative staff indices recorded
to CmdState._
