This problem is absent from 2.3.1 and 2.4.4.

Very early during conversion of a hashed mirror of the following
repository http://code.haskell.org/ddc/ddc-head , I get:

lossy conversion of complicated conflict:

darcs: Codec.Compression.Zlib: premature end of compressed stream


With darcs 2.3.1 and 2.4.4, the lossy conversion happens but darcs
convert continues until the end.

i've also seen this on another repo just now.

Needs investigation.  Guillaume, would you be interested it giving the
new darcs trackdown --bisect a try to see if it tells us anything
interesting?

I took branch-2.4 and pulled non-conflicting patches from HEAD and at
least I can say the folowing is not the problem:

* Reiner's UTF8 patches
* Florent's pul refactor, obliterate -o, fetch patches
* my patch about apply accepting gzipped files (resolve issue 1477)

Pulling more patches lead to conflicts or inconsitent patches.

Thanks for your debugging steps, Guillaume.  I've created a new ticket
issue1862 and moved your messages 11161-11163 onto there out of a sort
of conservatism.  In these messages you had simplified the repository
somewhat and triggered a new error message.  Out of conservatism, I'm
assuming these are two separate errors for now and we still need to
investigate the original Zlib-related error.

(For the curious, you can still see the messages in this ticket's
history at the bottom, so nothing is really lost).

This is really the same as 1862 and 1860. The message is different, but 
the underlying problem is the same.
