** Description changed:

+ [SRU]
+ 
+ [Impact]
+ Easily reproducable crash prevents users from modifying the disk devices when 
performing a custom install.
+ 
+ [Test Case]
+ 1- Start virt-manager
+ 2- Click new, go through the wizard to perform an install, but click 
"customize" on the last screen
+ 3- In new window, click on the disk section
+ 
+ Step 3 should crash without the fix, and should success with it.
+ 
+ [Regression potential]
+ The patch is pretty simple. If it is wrong, the disk section in the hardware 
screen on existing and new VMs could fail to operate properly.
+ 
+ 
  This happens if you do the customise VM before install and click on the Disk 
section.
  It sounds very similar to https://bugzilla.redhat.com/show_bug.cgi?id=978264
