Trying this on an Intel Mac OSX with

I downloaded and unpacked http://darcs.haskell.org/ghc-STABLE-2007-09-11-ghc-corelibs-testsuite.tar.bz2. 
After the darcs pull (Pulling from "http://darcs.haskell.org/ghc-6.8/ghc"...  This is the GHC darcs 
repository (ghc-6.8 branch)):

> thorkil-naurs-intel-mac-mini:~/tn/test/darcs/Issue/1022/work/unpack/ghc thorkilnaur$ darcs whatsnew
> No changes!

I tried to pull the GHC HEAD into this STABLE repository, both from http://darcs.haskell.org/ghc and from a 
local repository. In both cases, I interrupted the pull after it's having spent 100% CPU for more than an 
hour without apparent progress.

So this seems to be a dead end.

Right from the start, however, I had recognized the name of the file concerned (lambda-logo.png) and it 
turned out that I had run into a similar problem a while back, attempting to build the GHC HEAD on this 
FreeBSD machine:

> tn at tn21$ uname -a
> FreeBSD tn21.thorkilnaur.dk 5.4-RELEASE FreeBSD 5.4-RELEASE #0: Sun May  8 10:21:06 UTC 2005     
root at harlow.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386

Getting back to this (so far incomplete) attempt, I found:

> tn at tn21$ darcs --exact-version

which is a bit like the problem reported by Simon PJ. I also found these patches, related to the concerned 
file:

And:

I am unfortunately not 100% sure, but this repository was most likely created by starting with an archive 
ghc-HEAD-2007-12-16-ghc.tar.bz2 and pulling the GHC HEAD (as of 2008-May-03) into it.

I have tried to pull the present GHC HEAD into the repository created from this archive, but darcs whatsnew 
reports 'No changes'.

So: I have an existing repository with a problem similar to the one that Simon PJ had, but I have not been 
able to find a way to create such a repository.

Best regards
Thorkil
