Crash on very large chord

Discovered this while messing around.
Occurs with fresh installation of MuseScore 2.02 on Arch x64 (Qt 5.5.1) and Windows 10 x64 (Qt 5.4.2). Others untested.
No custom configuration done.

Reproduction:
Open MuseScore (settings all default, as if just installed).
In the Start Center popup, select Create New Score.
In the Create New Score wizard, click Cancel.
Press N to begin note entry.
While holding shift to create a chord, repeatedly press CEG in a sequence.
MuseScore will eventually crash. It seems to differ when it crashes, but almost always happens by thirty notes.

I've attached a log of the output from running `mscore -d` and invoking the crash.
