Short description of error
Plane Track Deform node fails to show output unless preview is visible in connected node.
I'm guessing you don't need the video but it's the fabric-eingang.avi found here:
http://projects.blender.org/scm/viewvc.php/trunk/lib/tests/tracking/footage/?root=bf-blender
Exact steps for others to reproduce the error
Open attached .blend
Click the backdrop button off and on again to redraw the screen.
Toggle node preview off (Shift-H) for the Image node and the Plane Track node result will disappear from backdrop.
The same thing happens if you connect any other node without preview to the Plane Track node input.

Looks like somehow the resolution is not propagated upstream to the image node by the plane track. It ends up with (0,0) resolution and doesn't give a valid output then.
