title: Subversion reports "Malformed Network Data" when updating repository over Cisco VPN
body: <p>I am using Cisco VPN (on Windows 7 Ultimate 64bit) to connect to my company network.  When I check out svn repositories, I constantly get this error 2 or 3 seconds after downloading some files.  </p>
  
  <p>The problem happens on both TortoiseSVN 1.5.9 and SlikSubversion 1.6.17</p>
  
  <p>I noticed that downloading text files like java or xml often causes this problem, but downloading compressed files(jar etc) is fine.</p>
  
  <p>Is my SVN or VPN setting wrong, or is this a network issue?  How can I make SVN log more details?</p>
  
  <p>PS: I am not using any SSL proxy in my SVN.  </p>
