OK, I'll try and do the same in mdv once I can actually get my system in
a vaguely working state due to all the changes of late... (rpm5 switch).
> PulseAudio #1 and #2: I believe these should be applied to PulseAudio
OK, I think you've given it sufficient testing and exposer to confirm
this. Can I just ask if these are "safe" if the corresponding gst fixes
are not committed? (i.e. will GST generally bork or should it cope as
well as currently without it's patches?) Also, master only or master+s-q
(I'm personally favouring the latter).

OK, I can ask my Skype contact to see if there is something we can do to
debug this further. Just ping me to discuss and we can take it from there.
