GUPNP: Failed to get SCPD: Cannot resolve hostname ((null))

The following message occurs when the <urlbase></urlbase> tag of the root device description is empty when trying to autoconnect actions:

** (process:25888): WARNING **: Failed to get SCPD: Cannot resolve hostname ((null))  

Changing it to http://localhost fixes the issue.

<?xml version="1.0"?>  
<root xmlns="urn:schemas-upnp-org:device-1-0">  
  <specVersion>  
    <major>1</major>  
    <minor>0</minor>  
  </specVersion>  
 <URLBase>http://localhost</URLBase>
  <device>  
    <!-- ... -->  
  </device>  
</root>  

The message is a bit misleading. I was first trying to find an issue with my DNS configuration.
