[darcs-users] patch tag problem, "hash failure in"

[Thomas Hartman]

Thanks Jason, your reply sent me on the right track. I believe this is
fixed now.

The problem was related to switch to happstack 4, but it wasn't really
a defect in happstack 4.

There was a place where I used a custom "myfileserve" function to
correct against a defect in happstack 3, and when I switched to the
blessed fileserve function in happstack 4 everything was shiny.
