Bug Report - Wenatchee 5 Build 2014-01-28 crash when typing a "-"

As I can’t find a followup for the command line when starting a command. I’ve had rhino crashing a few times.
I want to extrude a line or surface, I start the command and forget to select the line or surface and start typing “-4” when I hit the “-” key rhino crashes.

I can duplicate this. This will be fixed in the next WIP release.
