Even though the kate decoder plugin is installer it is not detected by gstreamer and/or dependent applications. The file I was trying to play is at [1].

onkar@iBook:~$ gst-inspect-0.10 katedec|head -35

Here is the output I get when trying to play the file with subtitles in kate format using playbin.

Also find attached the screenshot of totem's plugin search when I try to play the file.

The problem seems to be because katedec does not have a rank assigned. Hence playbin does not automatically plug the decoder. This was changed in upstream git at [2]. If someone can confirm that this works in latest updated Lucid, I will work on SRU for karmic.
