[Python-apps-team] Bug#919260: mu-editor: Missing dependency

[Uwe Steinmann]

Package: mu-editor
Version: 1.0.1+dfsg-1
Severity: important

Dear Maintainer,

when starting mu-editor, I get the following

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 581, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 898, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 789, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (matplotlib 3.0.2 (/usr/lib/python3/dist-packages), Requirement.parse('matplotlib==2.2.2'), {'mu-editor'})

During handling of the above exception, another exception occurred:
