[FFmpeg-user] ffprobe failure with videos from 1 of 2 identical cameras

[Gan Uesli Starling]

I have two identical Nikon CoolPix L20 cameras. Both have the same
firmware version of 1.0 (with no updates available).
Videos from both cameras play fine on both VLC, MoviePlayer and on
Firefox browser.
And yet ffmpeg & ffprobe accept videos from only one of the two
identical cameras. On all videos from identical 2nd camera they fail.

The two videos are available for download and examination here:
http://starling.us/ffprobe/
DSCN1330.AVI <-- This video works everywhere
DSCN0902.AVI <-- This video works everywhere EXCEPT on ffprobe and ffmpeg


Results for ffprobe are as follows. First the one that doesn't work,
then the one which does.

So, can someone tell me what the problem is and how to fix and/or work
around it?
