[Pkg-libvirt-maintainers] Bug#652879: virt-manager: Can't change disc bus when creating VM (Wheezy)

[Greg]

Package: virt-manager
Version: 0.9.0-3
Severity: normal
Tags: upstream

Dear Maintainer,

During a virtual machine creation, I wan't to customize the configuration
before installing.
If the disc bus is set to something else than "default", this error message
appear when validating :

Error changing VM configuration: 'NoneType' object has no attribute 'xpathEval'

Traceback (most recent call last):
