--- Operating System, Graphics card ---
Windows 7 32bits, Ati 4850pro

--- Blender version with error, and version that worked ---
2.66 oficial

--- Short description of error ---
I'm using the UV image editor after a render and I search border in the commands. I wanted to know if I could configure a border in the UV/image editor and by error I used "Border select" instead "Set Render Border" (option that we cannot see in the UV/image editor). When you make the selection blender crashes.

--- Steps for others to reproduce the error (preferably based on attached .blend file) ---
-Open blender
-Press F12 to make a render and see the UV/image editor.
-press SPACE
-search "Border Select" and use this.
- make the box
- blender crash.
