[15647] breaks mythtranscode (and maybe others)

[xris]

[15647] for #4265 seems to prevent the USN and SecurityPin fields from getting filled in for DefaultBackend in config.xml, which causes mythtranscode to segfault (and maybe other things), or maybe these fields didn't exist in the first place. Replacing the two fields from another config.xml on the same host (different userid) make the segfault go away.

Haven't reproduced yet, but a config.xml without USN+PIN should magically use UPNPautpconf, find a backend, and happily run. Like this:

^C

Does gdb mythtranscode reveal the location of the segfault?
