It looks like you have not recompiled, that line used to be:

      Just installed <- getInstalledPackages verbosity comp packageDB conf

it is now:

      installed <- getInstalledPackages verbosity comp packageDB conf

So there is no possibility of pattern match failure on that line any
more.

The change is definitely in the darcs repo, see:
