Broken: (example: 2.69.7 4b206af, see splash screen)
Short description of error
The last operator for the Rip tool has a double entry where one part is greyed out and one is not greyed out.
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
Open Blender, enter Edit mode. Select some vertices and use the Rip Tool. Hotkey V. Watch the Last Operator Rip.
This may be a cosmetic problem. But the greyed out part is at the top. And when you just see this part, which is the case with the default Blender layout, then you can get the impression that editing isn't possible at all.
