Preupgrade crash when resuming

UPDATE

Seth Vidal has a better solution. Rather than just catching the exception, you can prevent it by correcting the error in the code, as noted by Anonymous in the comments:

So the problem is that it tried to use _grabfunc, which doesn't exist, instead of grabfunc. Yay.

I was trying to upgrade to Fedora 12 today via preupgrade but had to stop my upgrade session due to a network issue. When I tried to resume, as you're supposed to be able to do, it started getting the metadata again and then it suddenly crashed!

That's obnoxious. I didn't want to restart it, as I'd already downloaded over a hundred MB of files. So, as root I looked at the file tripping the AttributeError, /usr/lib/python2.6/site-packages/preupgrade/__init__.py, and decided to catch the error:

    repo._grabfunc.opts.user_agent = __user_agent__            

became

try:                                                            
    repo._grabfunc.opts.user_agent = __user_agent__             
except AttributeError:                                          
    print "Can't set user_agent, repo._grabfunc = NoneType :( "

I then ran it again, and this caught two exceptions, but allowed me to proceed with seemingly no loss of functionality. I am now happily downloading still more amazing amounts of MB. Hurrah!

Now to file a relevant bug if it doesn't already exist. The oft duplicated, already existent RH bug is 538118.
