  error, called at src/Darcs/Patch/Conflict.hs:103:5 in darcs-2.18.3-5469898435c90cc53ddbdb01f4c15ff1619487ab9ba0b191543e64ba814b25a2:Darcs.Patch.Conflict

It is a large repository (8.3 GB, 20,705 patches) but darcs 2.16 has no problem with it.

%                    darcs --version
2.18.3 (release)

(Ubuntu/Linux)

I tried: 
* darcs optimize clean (no error but changes nothing)
* darcs get REPOS in an empty directoty (same error message)

Retrieving the patches one by one (with darcs pull -h HASH) works...
