Excepted behavior: No crashes, measures are deleted.
Actual behavior: crashes

Steps to reproduce bug
1. Create new score
2. Add Measures
Menu -> Add -> Measures -> Insert Measures -> Number of measures to insert: 2 -> OK
3. Open timeline (Menu -> View -> Timeline)
4. Try undo
If I swap step3 and step4, it still crashes.

Comments

Does master contain the same code for the timeline at all? The fix is purely in the timeline widget implementation, and all the code related to UI seems to be rewritten if I understand it correctly.

Status active fixed

Let's mark it fixed, as it is in the 3.x branch, and timeline is not (yet?) part of the master branch (which will become 4.0)
Pity that there won't be a 3.,6.3 or 3.7
