Programming :: Python Error - List Index Out Of Range (Web Scrapper)

Having a bit of an issue with Python while trying to write a script to download every rar file on a webpage. The script successfully downloads any link that doesn't contain any spaces, etc. But when it hits a url like: [URL] (Classical Spelling).rar. It fails...I'm sure this is something simple, but I'm so new to python I'm not sure what to do!

Code:
import urllib2
import os
os.system("curl [URL] -i rar|cut -d '"' -f 2 > temp.out ")
infile =open('temp.out', 'r')
for url in infile:
print url
#url = "[URL]"

#url = target
file_name = url.split('/')[-1]
u = urllib2.urlopen(url)
f = open(file_name, 'w')
meta = u.info()
file_size = int(meta.getheaders("Content-Length")[0])
print "Downloading: %s Bytes: %s" % (file_name, file_size)
file_size_dl = 0
block_sz = 8192

while True:
buffer = u.read(block_sz)
if not buffer:
break
file_size_dl += block_sz
f.write(buffer)
status = r"%10d [%3.2f%%]" % (file_size_dl, file_size_dl * 100. / file_size)
status = status + chr(8)*(len(status)+1)
print status,
f.close()
