pa_stream_get_timing_info() can sometimes return null, so we must protect ourselves against that in gst_pulsering_stream_latency_cb().

I believe I have fixed this bug. Can you check that it is actually fixed, by installing the version of gst-plugins-good-0.10 that is available in my ppa ( https://launchpad.net/~diwic/+archive/ppa )?

(Or at least it will be available once the ppa builders finish, which might take a few hours from now...)
