OSX, ATI 6770
Broken: 2.71 e1eb2e9
Short description of error
Adding a mesh without faces and entering edit mode keeps the ghost selection in faces mode, confusing the user (me).
Exact steps for others to reproduce the error
Add circle mesh, enter edit mode. Active selection is displayed as edges selection even though user may left and entered the edit mode in faces selection making any command unresponsive.
To be clear. Displayed selection is all edges (no center point), mode is faces selection. I assume that the selection mode is edges and get angry and throw stuff at the monitor because none of my shortcuts work, and curse at the Blender for messing up my shortcuts yet again (which it of course didn't do last time I encountered the bug either). The I glance at the edit mode and realize that the selection mode is faces (which mesh circle by default doesn't have).
