I try to clone a VM with this network configuration:

    <interface type='ethernet'>
      <mac address='52:54:00:38:53:95'/>
      <target dev='m0d0'/>
      <model type='e1000'/>
    </interface>

and get this error:

Error setting clone parameters: cannot concatenate 'str' and 'NoneType'
objects

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 664, in
clone_domain
    clone_window.show()
  File "/usr/share/virt-manager/virtManager/clone.py", line 142, in show
    self.reset_state()
  File "/usr/share/virt-manager/virtManager/clone.py", line 190, in

    self.populate_network_list()
  File "/usr/share/virt-manager/virtManager/clone.py", line 271, in
populate_network_list
    net_dev and " %s" % net_dev or "")
TypeError: cannot concatenate 'str' and 'NoneType' objects

The culprit seems to be the interface type. This configuration can be
cloned:

    <interface type='ethernet'>
      <mac address='52:54:00:38:53:95'/>
      <target dev='m0d0'/>
      <model type='e1000'/>
    </interface>

Sorry, I pasted the wrong configuration snipset.

A VM with this network configuration can be cloned:

    <interface type='bridge'>
      <mac address='52:54:00:38:53:95'/>
      <source bridge='virbr0'/>
      <target dev='m0d0'/>
      <model type='e1000'/>
    </interface>

Thanks for this bug report, and sorry for not following up earlier.
Can you still reproduce this with on current Debian stable, or
testing/sid?

Cheers,
