Have you set either of those files to reside outside of _darcs? If so, is it possible your other steps (such as the svn checkout) is writing over those files with regular expressions that darcs doesn't like? Really, it would be an expression that regex-posix doesn't like. If you haven't changed the default boring and binaries files to reside outside of _darcs, does anything change them in _darcs? Can you do a diff between a repo where you get the error and an repo where you do not? I'm thinking of the unix command diff, like: diff -u good/_darcs/prefs/binaries bad/_darcs/prefs/binaries Also, it's possible that the regexes to match against .svn directories is bad. I wonder how often they get tested. Those regexes would be in the boring file, by the way. I hope that helps, Jason
