Package: python3-matplotlib
Version: 3.5.2-2
Severity: serious
Something significant seems to have changed in version 3.5.2-2 of this
package, as it now breaks the spyder 5.3.1+dfsg-1 autopkgtests: see
https://ci.debian.net/packages/s/spyder/testing/amd64/
The tests passed with version 1.8.1-6.
The relevant lines of the log file are:
_____________ ERROR collecting spyder/app/tests/test_mainwindow.py _____________
ImportError while importing test module
'/tmp/autopkgtest-lxc.lani2ms0/downtmp/build.v6H/src/spyder/app/tests/test_mainwindow.py'.
Hint: make sure your test modules/packages have valid Python names.

The same seems to have happened to scipy in version 1.8.1-7, in case
that helps.
Best wishes,
