[jokosher-devel] Possible workaround for last critical bug

[John Green <john thegreens co uk>]

Attached is a patch with a possible workaround for our last critical bug 
69714. I haven't committed it as it is a workaround and might not work for 
everyone (it does for me). It also ignores some gstreamer error messages 
which might be a bit dangerous so it probably needs a fair amount of testing.

Since the recording does actually still occur it just ignores the error 
message from the bus. The test in TransportManager that the pipeline is 
paused is also bypassed so that the playhead moves again. Since the 
query_position is in a try do we really need this test anyway?
