Sorry, corrected package is now online.

No problem, just take the first 4 MByte or so (use dd's count= and bs= 
options, e.g. count=4096 bs=1024). This should be sufficient to see what 
happens.

If you already dd'ed the image to disk, did you try this?
# mount -t rbf -o loop /path/to/image /mnt
Would be interesting to see whether this crashes as well. You may also try
# mount -t rbf -o loop,verbose /path/to/image /mnt
dmesg may then write
RBF device loop0 sector size 512 cluster size 1 sas 0
RBF device loop0 free clusters 4693/62720 largest 369 fragmentation 0%
or similar.

Slow and unreliable is one thing, expensive is another thing. If it is 
not expensive, please try to dump the first 4 MByte or so, gzip them and 
make them available to me via ftp. This will probably help a lot.

Thank you for helping to trace this problem down.
