Description of problem:
When I tried to install Rocks Cluster Distribution 4.3, I got the following
message (copied by hand):
An unhandled exception has occurred. This is most likely a bug. Please copy the
full text of this exception and file a detailed bug report against anaconda at
http://bugzilla.redhat.com/bugzilla/

NameError: global net 'FileCopyException' is not defined

Version-Release number of selected component (if applicable):
10.1.1.63

How reproducible:
Always, on my Dell PowerEdge 1950

Steps to Reproduce:
1. Install Rocks 4.3 on my Dell PowerEdge 1950
  
Actual results:
The above error.

Expected results:
Rocks installs.

Additional info:
It's possible that I get the FileCopyException because the DVD image is bad.
Even if so, it looks like FileCopyException is used without being defined, so
it's still an anaconda bug.
