System Information
Win7/64, GTX 750 Ti
Blender Version
2.74 official, 2.75 build 42314b3
Short description of error
It seems there is still no agreement about how to display a scene's frame range. It changes forth and back now and then.
2.74 official: time line window correct, VSE incorrect
2.75 build 42314b3: both incorrect
Exact steps for others to reproduce the error
Start Blender and set start frame=0, end frame=9. These are 10 frames. The movie covers 10 full frames, not 9 frames. The UI should reflect this. In 2.74 official, the time line window displays it correctly whereas the VSE does not. In 2.75 build 42314b3 it's incorrect in both windows.
