   Without a more concise version number, it's difficult to say 
precisely what your problem may be.   Nevertheless, if it came from an 
SVN snapshot, you might be getting bitten by the upnp bug that cropped 
up in SVN for a while.

   I would suggest contacting the package maintainer and asking them to 
up-(or down-)grade to a newer (or older) SVN snapshot.   Until they get 
around to doing that, you might locate the script that is used to start 
mythbackend on your machine, and add the "--noupnp" flag to the line 
that invokes mythbackend.   See if your problem doesn't disappear.
