Bug#985154: gegl: autopkgtest regression: Package 'gegl-0.4' requires 'babl >= 0.1.84' but version of babl is 0.1.82

[Paul Gevers]

Source: gegl
Version: 1:0.4.28-1
X-Debbugs-CC: debian-ci at lists.debian.org
Severity: serious

Dear maintainer(s),

With a recent upload of gegl the autopkgtest of gegl fails in testing
when that autopkgtest is run with the binary packages of gegl from
unstable. It passes when run with only packages from testing. In tabular
form:

                       pass            fail
gegl                   from testing    1:0.4.28-1
all others             from testing    from testing

I copied some of the output at the bottom of this report. Reading the
changelog, I noticed that the Build-Depends on babl was bumped
appropriately, but it seems that *versioned* dependency is missing in
other places. This missing is also causing regressions in other reverse
dependencies [1]. Can you please investigate the situation and fix it?
