Yes. Actually it got worse (or just more reliable): I now managed to
hang virt-manager by opening/closing just a single VM window. Summary:

- VM #1 runs Linux (all the other VMs run Windows). Opening/closing just
  this VM causes virt-manager to hang reliably. 

- If I open multiple windows and then close them in the exact reverse
  order, then there is no hang.

- If close windows in any other order, then virt-manager hangs. That is,
  if I open 3 windows and close the second, it hangs.

  AFAIR 0.8.0 hung only when closing the window that was opened first;
  opening/closing subsequent windows did not cause problems as long as
  the first window was alive. OTOH 0.8.0 crashed sometimes instead,
  which 0.8.1 did not do so far.

- Even if I close all the windows in the "right" order and exit
  virt-manager normally, the ssh process to the remote machine remains
  there in the background.

- Even if I kill this ssh process, on the remote node an "nc -U
  /var/run/libvirt/libvirt-sock" process remains alive. Not sure if this
  is really a problem or not; at least killing these processes and
  trying again does not change anything.
