Comment 1 for bug 812516

This is the failing line in src/util.py:
for j in os.listdir(fd_path):

It dies with:
Traceback (most recent call last):
  File "./tmp/ufw/usr/sbin/ufw", line 111, in <module>

Simply wrapping that in a 'try' in enough to fix the bug. I'm guessing this is a result of the following in fakeroot:
fakeroot (1.16-1) unstable; urgency=low

  * Patch from Jonathan Nieder to add access() support.
