Bug#825621: gnat-4.9: empty Build-Depends-Indep field

[Steven Chamberlain <steven@pyro.eu.org>]

Package: gnat-4.9
Version: 4.9.3-3
Severity: important

Hi,

In gnat-4.9's debian/control file there is an empty field:

Build-Depends-Indep:  

Is this intentional?  Perhaps it should not be there at all.
I can't see that this is prohibited by policy, but it seems to be a
problem for `apt-get build-dep ./` :

Note, using directory './' to get the build dependencies
Reading package lists...
E: Problem parsing dependency: Build-Depends-Indep
E: Unable to get build-dependency information for ./

(This could also be a bug in apt-get, or in the policy).

Thanks.
