Confusing error message when notmuch setup is not completed

[The-Compiler]

I tried to run dodo without having notmuch set up properly yet:

$ notmuch search
Error: cannot load config file.

doing so results in a rather confusing error:

$ dodo
Error: cannot load config file.
Error: cannot load config file.
