Bug Description

Binary package hint: ipcheck

ipcheck version 0.233-1 gives

    Traceback (most recent call last):
      File "/usr/sbin/ipcheck", line 5518, in <module>
        _main(sys.argv)
      File "/usr/sbin/ipcheck", line 5198, in _main
        fp.close()
      File "/usr/lib/python2.6/socket.py", line 273, in close
        self._sock.close()
    AttributeError: 'NoneType' object has no attribute 'close'

Lines of interest are

    $ cat -n /usr/sbin/ipcheck | sed -n 5190,5198p
      5190 try:
      5191 fp = h2.getfile()
      5192 httpdata = fp.read()
      5193 fp.close()
      5194 except:
      5195 httpdata = "No output from http request."
      5196
      5197 # explicitly close
      5198 fp.close()
    $

It seems h2.getfile() is returning None causing problems when fp.close()
is attempted outside of the try-block.

Having had time to work around it, fp isn't None, but fp._sock is. Changing line 5198 to

    if fp and fp._sock: fp.close()

lets the program continue to apparently successful conclusion. I don't suggest this as the proper fix though. Without the work around, ipcheck.dat doesn't contain useful data.
