[virt-tools-list] [virt-manager] commit 5219e49e causes virt-manager hang

[Lin Ma]

Hi Cole,

It seems that commit 5219e49e caused virt-manager to infinite recursion 
in certain cases.
e.g: create new vm -> local install media -> select an iso(says fedora 
21 Server), Then the virt-manager hangs.


Not sure whether the following changes make sense, just FYI:
(actually I dont know which scenario meets the both of condition: 'if 
nothing is selected' and 'the widget is a combo box with a text entry')
