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: merger 0.0 ( hunk ./test/Graphics/N-Body/Boxed/Main.build 6 + +extra-link-lib-dirs: + /usr/X11R6/lib hunk ./test/Graphics/N-Body/Boxed/Main.build 6 + +extra-link-lib-dirs: + /usr/X11R6/lib ) lossy conversion of complicated conflict: merger 0.0 ( hunk ./test/Graphics/N-Body/Unboxed/Main.build 6 + +extra-link-lib-dirs: + /usr/X11R6/lib hunk ./test/Graphics/N-Body/Unboxed/Main.build 6 + +extra-link-lib-dirs: + /usr/X11R6/lib ) lossy conversion of complicated conflict: merger 0.0 ( hunk ./test/Graphics/Simple/Main.build 6 + + +extra-link-lib-dirs: + /usr/X11R6/lib hunk ./test/Graphics/Simple/Main.build 6 + +extra-link-lib-dirs: + /usr/X11R6/lib ) 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.
