MuseScoreNightly-2017-08-19-1918-master-ef25e60.7z crashes when switching to Jazz style on Win 10

• Aug 27, 2017 - 11:30

From time to time I have a look on the development versions. Over the last 4 weeks the nightlys crashes if I switch to MuseJazz style. I managed to set the text style to the jazz font. I can even format the title to MuseJazz Text font. This setting does not get saved, however. The next time I open the file it shows the title with the default font again.
When setting the title text ot MuseJazz Text font and then going to the general settings and also setting the musical symbols to MuseJazz the nightly crashes reproducably. I have attached the file.

Same happens when switching the Musical font to Bravura (but not when switching to Gonville).
Seems about time to get this reported in the issue tracker

I get
Fatal: ASSERT failure in QVector::operator[]: "index out of range", file C:/Qt/5.8/mingw53_32/include/QtCore/qvector.h, line 433 (:0, )

The crash when switching for other font is not the cause but the consequence of another issue (s), related to brackets, known issue: #240831: Edit arpeggios and spacers causes a crash and also probably to more general layout issue, involving here line breaks.

Ie, by deleting the bracket here, no more issue (need further checking nevertheless about the layout): 1) The Nearness of You.M3beta,mscz.mscz

EDIT: other aspect (or reverse case):
1) Grand staff template with line breaks
2) Switch to MuseJazz (in Musical symbols font)
First result: very unexpected: wide black trails onto the score (but not always, just a bit tricky!) :)

3) Drag and drop a bracket (brace)

Result: crash
