They were reported, not from me but from my collegue Tobias Rapp. As 
seen here:
https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2013-April/142201.html

SUMMARY:

At my point of view there were/are these problems with AVI:

1.) Carl Eugen mentioned: Seeking in large files with WMP fails 
sometimes, indicating that (afaict) something is wrong with the ODML index.
Carl, is there a ticket exisitng for this bug?

2.) Christoph Gerstbauer mentioned: Problem with AVI files where audio 
data is bigger than 2gb -> FIXED with ffmpeg version 2.1 -> bug is not 
reproducible anymore
     BUG REPORT: 
https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2013-April/142201.html
     FIX INFO: 
http://git.videolan.org/?p=ffmpeg.git;a=commit;h=7f09b888e88dcf063810378d411fa92ebbd7c36a

3.) Tim Nicholson mentioned INTERLACED FLAG problem in AVI:
     As I can see, the problem Tom mention regard to the "vprp chunk" -> 
The "FieldPerFrame" value is always "1".
     I never saw a AVI file with an value of "2" (interlaced). And I do 
not know about any ticket about this bug.

Example:
Chunk(vprp) {
             ChunkType: VideoPropertiesHeaderChunk
             Position: 0x000010F0, Size: 68
             VideoFormatToken: 0, VideoStandard: 0
             VerticalRefreshRate: 25, HTotal: 1920, VTotal: 1080
             FrameAspectRatio: 0x00100009 (16:9), FrameWidth: 1920, 
FrameHeight: 1080
             FieldPerFrame: 1
             FieldFramingInformation:
                CompressedBMWidth: 1920, CompressedBMHeight: 1080
                ValidBMWidth: 1920, ValidBMHeight: 1080
                ValidBMXOffset: 0, ValidBMYOffset: 0
                VideoXOffsetInT: 0, VideoYValidStartLine: 0
