Bug in Cabal creating user package.conf

I don't know if this has already been mentioned, but there's a bug in Cabal which I noticed when I tried to configure a package: $ runghc Setup.hs configure ... configure: Reading installed packages... cannot parse package list It turns out Setup created a user package.conf consisting of the two characters "[]" without a newline, which it was then unable to parse. Adding a newline fixed the problem. -- Ashley Yakeley, Seattle WA
