Aspect ratio wrong in rv40 video (after resolution change)

[xyzpublic]

Summary of the bug:
Change of dimensions of the source video seems not handled properly by ffmpeg/ffplay(git master) and vlc/2.01

ffmpeg gives scrambled output.
"ffplay -threads 1 src_with_dimension_change.rmvb" works, but ffplay without "-threads 1" doesn't.
vlc silently quits on dimensions change.

How to reproduce:

% ffmpeg -i src_with_dimension_change.rmvb output.avi
ffmpeg git master
built on ubuntu gcc 4.6.3

[rv40 @ 0x21f2b40] Width/height changing with frame threading is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented.

This part is a duplicate of ticket #1312

But the video aspect is wrong after the resolution change, it should be 4:3 but is undefined.

Ticket #1550 may be related.

There might be a seek problem with the file after resolution change as well. I can't get the file from the above ftp link and need the full file.
