System Information
Arch Linux, NVIDIA Quadro K5100M

Blender Version
Broken: 2.79 official and a51688d0b0
Worked: 2.78c

Short description of error
When rendering to a movie format using FFMPEG on a .blend file that was created at or before Blender 2.78c, Blender will crash if you choose to use the Quicktime RLE codec.

I made a debug build of a51688d0b0 and got the following GDB backtrace:

Exact steps for others to reproduce the error

Open Blender
Load the startup.blend attached to this report
In the Output panel of Render Properties, change Format to FFMPEG video
In the Encoding panel, change codec to QT rle/Quicktime Animation (container and audio codec don't seem to matter)
Render animation (Ctrl+F12)
Observe crash

Crash was confirmed on IRC by @jensverwiebe

I use a quickfix for now cause it seems rle is always handled/expected with alpha in blender:

I can confirm this is still an issue in current master (3994084e6a).

As a workaround, select RGBA as color model in Blender. It basically does the same as @jensverwiebe 's fix, without having to touch the C code and rebuild Blender.

@dr.sybren can you fix this then? It shouldn't be too hard to just always write RGBA under the hood if that is all we support.

@LucianoMunoz I also fixed it properly in D5174. It's probably safest to keep that for 2.81, but then writing RGB is also possible with QTRLE (and it is also a bit faster).

Writing RGB with QTRLE is now also possible, as D5174 is now in master. And WebM+VP9 also has proper alpha support now.
