When the file is accessed through HTTP the metadata is parsed before the first
buffer has to be pushed. But this is not the case if the file is local. Perhaps
this is related with how the src element operates? I wonder :)

To answer your question, yeah, it might be good indeed to queue buffers until
the metadata is parsed, I'll revise the patch.
