Test "signature verification (notmuch CLI)" fails (0.25.3)

[Kai Harries]

Hello,

on my system (NixOS unstable) the Notmuch test fails with the following
output:

 FAIL   signature verification (notmuch CLI)

                             }

I am building Notmuch 0.25.3 against gmime 3.0.5. Is this something I
should worry about? Is there something I can do to fix this?

Best regards
