Description James Laska 2010-09-20 17:08:52 UTC 
+++ This bug was initially created as a clone of Bug #595659 +++

The following was filed automatically by anaconda:
anaconda 13.21.45 exception report
Traceback (most recent call first):
  File "/usr/lib/anaconda/iw/examine_gui.py", line 122, in getScreen
    self.root = self.parts[0]
  File "/usr/lib/anaconda/gui.py", line 1415, in setScreen
    new_screen = self.currentWindow.getScreen(anaconda)
  File "/usr/lib/anaconda/gui.py", line 1327, in prevClicked
    self.setScreen ()
IndexError: list index out of range

How reproducible:
always

Steps to reproduce:
0. You must have *Fedora* installed on the disk, so you can see the ugprade dialog during the installation
1. Start VNC installation
2. When you're in stage2, click next until the partitioning dialog. Choose there "use existing partitioning layout" and select "review and modify partitioning layout"
3. Select disks you want to use and click next.
4. After you see the partitioning layout, click back until you get to the first welcome screen.

Result:
You can't go back to the first step, traceback is thrown in the time "upgrade screen" should be displayed.

Expected result:
User can go back to the first step

I can directly reproduce it in kvm even without VNC.
