--- Operating System, Graphics card ---

I tried this file in several computers with the same result: crash , W7 and Linux

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

2.66 official release 64 bit

--- Short description of error ---

when this file has an output node connected in some of the channels it crashes, the channels usually are alpha, depth and UVs, maybe some others as well...

--- Steps for others to reproduce the error (preferably based on attached .blend file) ---

just hit the render button and you should see a crash, if it doesn´t crash please change the output folder manually into a different one and try again, it should crash.

This is a report from mfoxdogg using Linux:
