Crash when exceeding the number of measures

Nightly (8cc66dd) / Windows7

1. New score of 5 measures (it is for the example )
2. Enter few notes in the two first measures
3. Select this group of two measures, then, use the « R » key for repeat.

If you are dizzy (it can happen!), and that you repeat two times (while six measures are required):
Result: crash.

- The version 1.3 behaves better, without crash, in this same case: adds by itself the sixth missing measure, and then refuses to continue.
