Right now several decoder and output plugins are more or less broken. 
For example, "mmsh:" links kill any gstreamer-based player[1], first off 
I thought it could be the wma decoder but there is also the issue with 
sound output.
As well, I can't play HTML5 audio reliably anymore. As the browsers I 
use (google-chrome, opera-next) have their own built in decoders, it all 
reduces to an output problem, that points to gstreamer-pulseaudio, this 
is probably a different bug, but I suspect it is somwhow related.

An example of failing "mmsh:" links. Save as a pls file and feed it to 
totem or whatever.
