Bug Description

Hi,

MLDonkey has a very serious bug which leeds to uploading
data blocks twice to eMule clients.

This is due to the fact that MLDonkey gets confused by
eMule rotating block request scheme.

http://hydranode.com/docs/ed2k/ed2kproto.php#upload
> Namely, eMule (and compatible) clients use "rotational chunkrequest" scheme,
> where each REQCHUNKS packet contains one new chunk and two older chunks
> ...
> This can lead to duplicate data being sent by mldonkeys, if a rotational
> chunkrequest scheme is used when communicating with them.

More infos about it, including logs proving the problem, can be found here:
http://mldonkey.sourceforge.net/forums/viewtopic.php?t=4576

On https://savannah.nongnu.org/patch/index.php?5664 you will find patches
for all MLDonkey versions since 2.6.0. I tested the patch with 2.6.0,
without it it uploaded 700MB for a 350MB file to eMule 0.47c, with the
patch it send 350MB, nothing more.

Please update the MLDonkey package in Ubuntu dapper.
I am posting this seperate ticket as advised in
