So, I had another look and it seems to work ok.  Not sure what you meant with
"otherwise pre-rolled" but the reason it works is that collectpads keeps the
subtitle pad in waiting-state (and as such will not trigger header writing)
until it receives a subtitle buffer or a subtitle segment (telling it there
will not be a buffer for some time).

As such, it will correctly receive the needed info (i.e. clut-event) as long as
that event is received before a buffer or a (future) segment event [*].  In
particular, the confusing part here is that (afaics) this is not related to any
1.x changes and should also have worked (without header rewriting) in 0.10
provided [*] holding up.  And it should have held up, unless some bug in
collectpads or some demuxer (??)

Anyway, so much "for the record".
