Comment 6 for bug 1085918

Thank you all for the comments.

@Max: Can we not change getarch() function to be more flexible rather than being so strict in its assumption of the media-info file format. i.e. Assuming that two arch strings wont be present in the infofile at the same time, rather than looking at a specific location for arch can we not do something like,
               if 'i386' in open(self.infofile).read()
                   arch = 'i386'
                  etc.?
