Package: diffoscope
Version: 101
Severity: important

Since the upload of colord 1.4.3, the diffoscope testsuite fails with:

We would normally:

 1. Update the expected diff for this latest version.

 2. Add a minimum version check directive for pytest.

However, the `cd-iccdump` command has no --version command and, whilst
the `colord` binary does, it relies on the daemon running to return any
output.
