**System Information**
Archlinux
GTX 460
**Blender Version**
Broken: 2.71 RC2
Worked: 2.68a
**Short description of error**
Snapping vertices with a subserf modifier doesn't work very well in RC2.
**Exact steps for others to reproduce the error**
1. Open {F94592}
2. Press G and hold Ctrl while moving the cursor over one of the vertices on the cube. In 2.68a it's super easy to get it to work, but in RC2 it almost never snaps.
