Affects: serpentine (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
May be a gstreamer bug, when started from the commandline there's an
error:

(serpentine:9336): GStreamer-CRITICAL **:
Trying to dispose element capsfilter1, but it is not in the NULL state.
You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.

after pressing the "write playlist to disc" button - there is no user-
visible GUI response, serpentine just keeps running.
