Hang on quit after uPNP access
This seems to be a generic uPNP / DLNA problem running VLC on OS X 10.8.3 and 10.8.4 (and perhaps prior versions as well, I don't know.)
I have tried streaming DLNA content from Twonky 4, Twonky 5, Twonky 6 and MediaTomb running on 2 different servers. VLC will pick up the server under Universal Plug and Play and play the content perfectly with all setups, but in EVERY case, VLC will lock up when I try to quit VLC. The is 100% repeatable.
I have tested this on VLC 2.0.7 and also 2.1.0-pre1 20130626-0117 and the behaviour is identical. VLC lockup on quit after playing DLNA content. Beachballing permanently and requiring a Force Quit to terminate the application.
Searching the VLC forums I see others reporting the same problem on OS X with version 2.0.1 on both Windows and OS X platforms.
