Comment 6 for bug 1011194

The stack trace would be more readable with the libdbus debug symbols. In any case, it seems that VLC is stuck waiting for your desktop inhibit service to respond to a screensaver inhibit request. This prevents the video output thread from terminating, which then prevents the playlist from moving on and the UI from exiting.

From my point of view, that is a bug in your desktop environment, or whatever components provides the screen-saver inhibition D-Bus API (can't say which without VLC logs).
