[request-tracker-maintainers] Bug#835536: request-tracker4: FTBFS with gnupg 2.1

[Dominic Hargreaves]

Source: request-tracker4
Version: 4.2.12-6
Severity: serious
Justification: FTBFS

Now that libgnupg-interface-perl has been fixed to use gpg1 (
see #834281) request-tracker4 still FTBFS because it configures
GnuPG::Interface to use 'gpg' as the binary anyway. 

I intend to patch out this functionality so that request-tracker4
can work without hardcoding the path to gpg (which will avoid the
need to fiddle with this setting for backports).

Dominic.
