Bug#876257: libwebkit2gtk-4.0-37: blocks upgrade path for libgstreamer-plugins-bad1.0-0 1.12.3

[Antonio Ospite]

Package: libwebkit2gtk-4.0-37
Version: 2.18.0-2
Severity: important

Dear Maintainer,

it looks like libwebkit2gtk-4.0-37 is blocking the upgrade path for
libgstreamer-plugins-bad1.0-0 1.12.3, looking at the package
dependencies I spotted these constraints:

libgstreamer-plugins-bad1.0-0 (>= 1.12.2), libgstreamer-plugins-bad1.0-0 (<< 1.12.3)

which explain the issue.

However I am not sure about why both constraints are there.

Thanks,
   Antonio
