Hi,

I have a problem which seams to be similar to issue 364. I have compiled
darcs 1.0.9 using ghc version 6.6.1 (I'm using Ubuntu 7.10 package
ghc6_6.6.1-2ubuntu2_i386.deb).
I'm getting flowing error when I try to get remote repository (darcs
1.0.9 was installed in
/home/jam/usr/bin and darcs 1.1.0pre1 was installed in /home/jam/usr2/bin)

I do not get this error when I copy repository to local machine and
then use 'darcs get'.

I also get this error using 'darcs repair'.
