seek to 0 & query_position

The attached test (1) sets a custom text-sink which is a bin ("subparse !
appsink"), (2) set the pipeline state to PAUSED, (3) seek to 0, and (4) query
position. The query fails as expected when the text-sink is not set. But with
the custom text-sink, the pipeline suddenly goes to the end position of the
subtitle.

duncan:~/tmp$ tail test.smi
   <SYNC START=13000>
      <P>13000
   <SYNC START=14000>
      <P>14000
   <SYNC START=15000>
      <P>15000
   <SYNC START=100000>
      <P>100000
</BODY>
</SAMI>
duncan:~/tmp$ ./testpause4 file://`pwd`/test.avi file://`pwd`/test.smi
2>/dev/null
position: 0000100000000000
duncan:~/tmp$ 

If I set the render callbacks of the appsink, it receives all parsed subtitles
instantly on PAUSED state.
