[Pkg-libvirt-maintainers] Bug#832454: virt-manager doesn't open

[Michel Le Bihan]

Package: virt-manager
Version: 1:1.4.0-2
Severity: grave
Justification: renders package unusable

When I run virt-manager or virt-manager --debug --no-fork, virt-manager doesn't
open and I get that output in the terminal:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-manager", line 33, in <module>
    from virtinst import util as util
  File "/usr/share/virt-manager/virtinst/__init__.py", line 89, in <module>
    from virtinst.distroinstaller import DistroInstaller

  File "/usr/lib/python2.7/dist-packages/requests/__init__.py", line 61, in

    from .packages.urllib3.exceptions import DependencyWarning
ImportError: cannot import name DependencyWarning

This issue is also present in the package in testing (1:1.3.2-4)
