[Nix-dev] ghc-mod fail errors: bug: gmeioException

[Carlo Nucera]

Hi all, I recently did a `nix-channel update` and a reinstall of my
programs, and now I have in emacs+ghc-mod this problem:

Fail errors:

BUG: GMEIOException /home/carlo/code/haskell/helios/dist/setup-config:
hGetContents: invalid argument (invalid byte sequence)

After a brief search, it's probable that the issue is caused by the
new version of cabalInstall.
(see https://github.com/kazu-yamamoto/ghc-mod/issues/417)

Anyone has had the same problem on nixOS?

Best Regards
Carlo
