I could not reproduce this, but I swear it happened to me in one of my
repos with HEAD after 2.5 and prior to Darcs 2.8
Basic pattern is
rm -rf someDirectory
darcs record someDirectory
[complaint that the directory does not exist]
We're waiting on somebody who can make this sort of thing happen again
BTW, I'm pretty sure the message you get is the same as when you record
a non-existing file:
WARNING: File 'x' does not exist!
Recording changes in "x":
darcs failed: None of the files you specified exist!
