Description of problem:
  if file '.listing' exists in the local directory when wget retrieves 
  directory listing, it crashes with
  "*** glibc detected *** wget: double free or corruption"

Version-Release number of selected component (if applicable):
  1.10.2-3.2.1, 1.10.2-7

How reproducible:
  always.

Steps to Reproduce:
  $touch .listing
  $wget ftp://kernel.org/

  this time wget magically survives even the pointer is freed twice. somewhere
  before the call to free() a new chunk of memory is allocated at the 
  address stored in the pointer. listing data is stored in index.html[.x]

  $wget ftp://kernel.org/

  now wget finally crashes.

attaching patch that should fix this.
