Verbose output of what?

I don't think i'm using a sbuildrc and all settings in sbuild.conf seem 
to be commented out.

Yeah, I noticed that, unfortunately it doesn't help me determine why.

stretch/sid's version of fltk1.3 uses build-depends arch and was in the 
build-attempted state on our autobuilder system when I got back to 
having another look at this issue.

Anyway I think i've found the problem.

         if ($self->get_conf('BUILD_ARCH_ALL')) {
             push(@positive_arch, $deps->{'Build Depends Arch'})
                 if (defined($deps->{'Build Depends Arch'}) &&
                     $deps->{'Build Depends Arch'} ne "");
             push(@negative_arch, $deps->{'Build Conflicts Arch'})
                 if (defined($deps->{'Build Conflicts Arch'}) &&
                     $deps->{'Build Conflicts Arch'} ne "");
         }
         if ($self->get_conf('BUILD_ARCH_ALL')) {
             push(@positive_indep, $deps->{'Build Depends Indep'})
                 if (defined($deps->{'Build Depends Indep'}) &&
                     $deps->{'Build Depends Indep'} ne "");
             push(@negative_indep, $deps->{'Build Conflicts Indep'})
                 if (defined($deps->{'Build Conflicts Indep'}) &&
                     $deps->{'Build Conflicts Indep'} ne "");
         }

Theres the smoking gun, it only installs Build-Depends-Arch if you are 
building arch all packages. So it looks like if you are not building 
arch all packages and the package has Build-Depends-Arch it breaks.

Looks like the soloution is to upgrade to the jessie-backports version 
of sbuild where this code seems to have been fixed.

What I don't understand is why it is working for Debian. Maybe the 
Debian buildds have been monkeypatched without changing the version 
number or something.
