There was a weird hack in kateenc that was messing up the buffers durations : 

-  /* Hack to flush each packet on its own page - taken off the CMML encoder
element */

This was breaking seeking in a matroska file containing kate encoded subtitles
for example with vlc, since the total track duration was completely wack...

I do no understand what  " flush each packet on its own page" could mean...
unless it was like each subtitle buffer would display on a different frame but
still it makes no sense to have the wrong duration..  I checked the CMML
encoder.. found no reference or any similar code...  

Also, I think if there was really a problem with the duration it should be set

So unless somebody has a clear idea why this is needed ?  

Here's a patch to fix it by removing this "hack"
