Bug#513315: Times out waiting for index to be rebuilt

Thanks for figuring out which package was causing the problem. python-apt is setting the default timeout so that it will time out if downloading a changelog takes too long. The attached patch modifies it to change the default just as long as necessary. It's racy, but I think it will work in this case. Once python-apt requires Python 2.6, it can use urllib2.urlopen's optional timeout parameter instead. [..] Thanks, this is part of my bzr tree and it will be part of the next upload.
