>gst_pad_query incorrectly returns 0 for the total number of sectors. I also
>would venture to guess that gst_pad_convert() fails for converting a 
>track index (track_format) to an end sector (sector format), but am not
>sure if that is because the query fails, or if because all sector-related
>code in the plugin or cdparanoia is broken.
>
>Insert an audio CD in /dev/hdc (or change DEVICE below), wait for it to 
>spin up and settle down, and then run this program. The number of tracks
>(n_tracks) on the CD should be valid, but total_sectors will be 0.
