I don't think upgrading will help.  I saw similar problems on my
Windows machine when using darcs built from the darcs repository for
darcs. (as of Dec. 20 2006 or thereabouts.) In particular, the first
problem always happens when there are conflicts, doesn't it? At least,
I know I've seen it before and the "solution" was to manually
binary-search for the conflicting patch and avoid pulling it.

Cheers,
Kirsten
