virt-manager does not start

Since yesterday's update virt-manager does not start anymore. Starting from terminal gives the following error:

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 41, in <module>
    from virtinst.uri import URI
  File "/usr/share/virt-manager/virtinst/uri.py", line 23, in <module>
    from .cli import parse_optstr_tuples
  File "/usr/share/virt-manager/virtinst/cli.py", line 38, in <module>
    from .clock import Clock
  File "/usr/share/virt-manager/virtinst/clock.py", line 20, in <module>
    from .xmlbuilder import XMLBuilder, XMLChildProperty, XMLProperty
  File "/usr/share/virt-manager/virtinst/xmlbuilder.py", line 28, in <module>
    import libxml2
  File "/usr/lib/python3.6/site-packages/libxml2.py", line 1, in <module>
    import libxml2mod

To me this looks like a python problem but I could not resolve it so far. Any ideas?

Re: virt-manager does not start

I hit the same problem.

$ id
uid=1000(mhk) gid=100(users) groups=100(users),10(wheel),91(video),92(audio),994(libvirt)
$ virt-manager

    import libxml2mod
ImportError: dynamic module does not define init function (initlibxml2mod)

After a long time I wanted to use virt-manager and saw the exact same error. I did try to remove virt-manager, purge all orphans and reinstall said package. No luck.

Then by chance I did a probably stupid thing:

sudo virt-manager

And the GUI showed up.

Now, I have no clue what's the source of the problem, but I guess this is a permission issue. Anyone else can reproduce this?

Re: virt-manager does not start

File "/usr/lib/python3.6/site-packages/libxml2.py", line 1, in <module>

The python 3 version of the module is being used instead of python 2.  Have you got any environment variables set that would affect python?
Edit:
Just had time to install it here,  starts without error under a normal user.

$ virt-manager
