failure trying to add PCI device to guest

Description of problem:
Invalid device is added to the xml for the guest when using virt-manager to add a PCI device to a guest.
Trying to add 04:10.0 on my system results in 04:16.0, so it seems and an unnecessary dev->hex conversion is done. The device appears to be added correctly, but when starting the guest, I get the following error:
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/engine.py", line 799, in run_domain
File "/usr/share/virt-manager/virtManager/domain.py", line 1256, in startup
File "/usr/lib64/python2.6/site-packages/libvirt.py", line 317, in create
if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: this function is not supported by the hypervisor: Failed to read product/vendor ID for 0000:04:16.0
If I used 'virsh edit rawhide-test' to edit the slot back to 0x10, the guest boots just fine.
Version-Release number of selected component (if applicable):

Should be fixed by the libvirt version in updates-testing.

Thanks, Cole. Does this problem exist in RHEL6 too?
Nope, RHEL6 libvirt is several releases ahead and has this fix already.
