Yes! `-no-user-package-db` does the trick.

I have to admit I had forgotten completely about the user DB. When 
running `cabal sandbox hc-pkg list` I only see the global one and the 
one in the sandbox. But `ghc-pkg` shows the user DB and indeed it 
contains `hashable-1.2.6.1` which was causing me trouble.

Cool, problem solved.

Would it make sense then for `cabal-cargs` to always emit 
`-no-user-package-db` when it discovers a sandbox?

Cheers
