gpg-related crash with custom formatter (BUG: gpg-interface.c:915: invalid trust level requested -1)

I use this one:

[format]
        pretty = %C(yellow)commit %H%C(auto)%d%Creset%nAuthor: %an <%ae> 
%C(yellow)% GK %GS %C(auto)[%GT% G?]%Creset%nDate:   %ad%n%n%w(0,4,4)%s%n%w(0,
4,4)%+b

When I now run "git log" in a repository that contains commits signed by 
people not in my keyring (e.g. the Gentoo git) I get this backtrace:

BUG: gpg-interface.c:915: invalid trust level requested -1

This is not absolutely new, it is broken for a while but I was too lazy to 
report (sorry about that). It has worked in the past, i.e. when I created that 
formatter (IIRC at least 2 years ago).

System is an openSUSE Tumbleweed installation on amd64.

Greetings,

Eike
