virt-manager.log when trying to clone

Description of problem:
I try to clone a paused, or shut down VM with virt-manager. When I select the clone option I get this error:

Erreur lors de la définition des paramètres du clone : Could not use path '['/dev/data/cos5-clone']' for cloning: 'LogicalVolume' object has no attribute 'format'

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 744, in clone_domain
    clone_window.show()
  File "/usr/share/virt-manager/virtManager/clone.py", line 138, in show

    (devpath, str(e)))
ValueError: Could not use path '['/dev/data/cos5-clone']' for cloning: 'LogicalVolume' object has no attribute 'format'

This VM is installed on a LVM logical volume (pool name data, volume group /dev/data)

Version-Release number of selected component (if applicable):

libvirt 0.7.1 (running on a CentOS 5.4 x86_64 host)
virt-manager 0.8.0-7 (from http://markmc.fedorapeople.org/virt-preview/f11/x86_64/) on Fedora 11 x86_64

How reproducible:
Always. At least when disk is backed by an LVM pool (haven't tried with file as backend)


Steps to Reproduce:
1. 
2.
3.
  
Actual results:
Get a traceback


Expected results:
Clone should work

Additional info:
on another desktop running ubuntu, I used a slightly older release (0.8-3) for virt-manager, from the same repo, converted to .deb using alien. Cloning is working.
