I haven't looked into this, just filing report now while I have generated segfault stack trace in latest master 3d280f2:

Note: the original I made in musescore a few years ago, so I'm also attaching the pdf I used for online import:

FYI, when I import that .mscz into 2.1, I get complaints about corruption:

Measure 14, staff 1, voice 2 too long. Expected: 6/8; Found: 1/1
Measure 16, staff 1, voice 2 too long. Expected: 6/8; Found: 1/1
Measure 22, staff 1, voice 2 too long. Expected: 6/8; Found: 1/1

And I'm able to continue the import. Although the score is mostly incorrect (most primary issue being that the original was 12/8, and result is 6/8)...that is probably an error with the Audiveris pdf import code and not musescore. Regardless, the segfault is still present in master and needs to be resolved (musescore probably needs to popup an error about corruption).
