-k option doesn't work: gpg: skipped "Oibaf <email address hidden>": secret key not available

[Oibaf]

The -k option doesn't work (using 0.143ubuntu0.2). As a workaround I can use the precise version, adding -kMYKEY in /usr/bin/backportpackage to the debuild command line and it works fine. Here is what I get (original Italian error):
