Bug#722355: libgtk2.0-0: triggers ci file contains unknown directive `interest-noawait' (needs newer dpkg)

[greg]

Package: libgtk2.0-0
Version: 2.24.20-1
Severity: important

Dear Maintainer,

Upgrading to libgtk2.0-0 on a legacy system wedges apt due to an
undeclared dependency on a newer version of dpkg (1.17?).

It is traditional, if not release critical, for inter-package
dependencies to be explicitly declared.  A "Pre-Depends" will solve the
problem for the many users who will soon stumble onto this issue due to
wide-spread dependencies on gtk2.  There are other solutions, but an
unstated dependency on someone else globally fixing the problem is not
really one of them.

See bug #714409 and bug #709443 for the same problem in gtk3 and texinfo,
respectively.
