Bug#1005779: djangorestframework: autopkgtest needs update for new version of pygments

[Paul Gevers <elbrus@debian.org>]

Source: djangorestframework
Version: 3.12.4-2
Severity: serious

Dear maintainer(s),

With a (not so) recent upload of pygments the autopkgtest of 
djangorestframework fails in testing when that autopkgtest is run with 
the binary packages of pygments from unstable. It passes when run with 
only packages from testing. In tabular form:

                       pass            fail
pygments               from testing    2.10.0+dfsg-1
djangorestframework    from testing    3.12.4-2
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of pygments to 
testing [1]. Of course, pygments shouldn't just break your autopkgtest 
(or even worse, your package), but it seems to me that the change in 
pygments was intended and your package needs to update to the new situation.

If this is a real problem in your package (and not only in your 
autopkgtest), the right binary package(s) from pygments should really 
add a versioned Breaks on the unfixed version of (one of your) 
package(s). Note: the Breaks is nice even if the issue is only in the 
autopkgtest as it helps the migration software to figure out the right 
versions to combine in the tests.
