Hello ! 

This is what I did

[zaleski@bipbip GetparC]$ darcs pull --dry-run --verbose
darcs: bug in darcs!
Impossible case at Pull.lhs:194 compiled 16:31:41 Mar  3 2006
Please report this to bugs@darcs.net,
If possible include the output of 'darcs --exact-version'.

and here is the version: 

darcs compiled on Mar  3 2006, at 16:32:49
# configured Fri Mar  3 16:27:51 CET 2006
./configure --with-static-libs

Context:

[TAG 1.0.6

Thanks for that.  Try it out it with 1.0.8, please.  We think it's been
fixed.

Best,
