Package: libgegl-0.4-0
Version: 0.4.18-2
Severity: grave
Dear Maintainer,
I attempted to use GIMP, but got this error in return:
gimp: symbol lookup error: gimp: undefined symbol: gegl_rectangle_subtract
The libgegl-0.4-0 package was the issue, as I wasn't able to install it because
of it's dependency on an available package.
It requires libgegl-common (>= 0.4.18-2) but 1:0.4.16-dmo2 is all that's to be
installed.
What I find odd is the apt policy for libgegl-common:
libgegl-common:
Installed: 1:0.4.16-dmo2
Candidate: 1:0.4.16-dmo2
Version table:
*** 1:0.4.16-dmo2 100
100 /var/lib/dpkg/status
0.4.18-2 500
500 http://deb.debian.org/debian unstable/main amd64 Packages
500 http://deb.debian.org/debian unstable/main i386 Packages
So I tried installing the available version using package=version, and APT
considered it a downgrade.
Should be easy to fix the candidate, but unusable at the moment if you don't
force "downgrade" it.

You are using libgegl from deb-multimedia.org, which is incorrectly
versioned, breaks the Debian dependency system, and regularly breaks GIMP.
It has an epoch, which means it is pretending to be newer than any version
in Debian, even when the version in Debian has new APIs like
gegl_rectangle_subtract() and the version on deb-multimedia.org does not.
This is not a Debian bug. I recommend not using deb-multimedia.org packages.

This is because deb-multimedia.org has (apparently deliberately) broken
version comparisons by adding an epoch, to force their version of libgegl
to be installed.
This cannot be solved without the cooperation of the deb-multimedia.org
maintainers: if we work around this in Debian by adding the same 1:
epoch, then deb-multimedia.org will presumably increase their epoch to 2:
to force their version to be installed again, breaking GIMP again.
