I can't reproduce, no crash here, just works as expected (Windows 7, MuseScore 3 Beta)

Hmm, try exporting a second time.
If that doesn't trigger the bug, then it might trigger on Linux but not Windows.
Depends on the format here (Windows10, Beta version)
Works as expected with PDF, MID, PNG (maybe others)
And crashes with MP3, WAVE, MusicXML (maybe others)
Same result with the current revision: 1b1912d
And I of course used PDF ;-)

FLAC export also crashes.
Reproduces on OS X. Crashes in Part::midiPort() because instrument()->channel(0)->channel() returns -1.
Is this perhaps the same issue as #278918: MIDI export of a part crashes?
Probably not, MIDI is confirmed to work in this issue, further up
MIDI export of parts crashes for me too, this may depend on platform probably.
Anyway this patch seems to prevent all these parts export crashes: https://github.com/musescore/MuseScore/pull/4389.
Though it would probably be good to have another solution for this.
