Problem extracting FS - Need Help

[sentrme]

I am getting an error when I try to extract the knoppix file system.

extract_compressed_fs image/KNOPPIX/KNOPPIX > tmp.iso

This is the last part of the text output that I get.
Block 1438 length 26298 => 65536
Block 1439 length 17569 => 65536
Block 1440 length 16103 => 65536
Block 1441 length 84 => 65536
Block 1442 length 84 => 65536
Size 1933270171 for block 1443 (offset 73449514) too big

I have search all over the internet trying to find what is going on.  I was able to extract the normal KNOPPIX filesystem just fine and it is a much larger filesystem.  Can someone please help?  I am trying to get this done as soon as possible, but I can not get past this part. 

Also, can someone break down and explain this command line:
(cd image; find . -size -10000k -type f -exec cp -p --parents '{}' ../master/ \;)

Does this command have anything to do with the extract_compressed_fs command?

I found the problem.  It was a bug in the newest version of Cloop utils.  I used an older version of Cloop and it worked fine.

The real problem was I was trying to extract the FS from the mounted image.  When I copied the KNOPPIX image to a local directory it extracted fine.

I hope this helps someone out in the future, it took me days to figure this out.
