If at any point a render/animate command is used on a sequence (video) to output to ffmpeg, Blender dies and loses all work in current state.

Thought this might be relevant. Seems that the blender binary which is pre-compiled and available from blender.org will render correctly. Some snooping leads me to believe that this is an ffmpeg backend issue. The binary which works has a static ffmpeg library built in. Is it possible to build ours this way? Or does this raise an eyebrow from someone who is more familiar with these products? I'm willing to do testing to help get this sorted but know very little with regards to how these particular libraries are built/used.
Please try again with blender-2.63a and reopen if it's still an issue. Thanks, Diego
