It appears to be XVideo, unless I am reading this incorrectly:

When I resize, the kmix video slider does not move, I loose audio, but
still have a picture.
When I switch sources, the slider goes all the way down to zero (the mute
position, I assume), then back to the current position, and I get both
audio and picture.
When I exit, the slider goes all the way to the mute position.
Here is what I get when I resize:
QtVisionView::resizeEvent()
haze font resized to 29
haze font resized to 29
QtVisionView::resizeEvent()
haze font resized to 30
haze font resized to 30

I hope this helps to narrow it down,
Thank you :-)

Random Thought:
--------------
If you have received a letter inviting you to speak at the dedication of a
new cat hospital, and you hate cats, your reply, declining the invitation,
does not necessarily have to cover the full range of your emotions. You must
make it clear that you will not attend, but you do not have to let fly at cats.
The writer of the letter asked a civil question; attack cats, then, only if
you can do so with good humor, good taste, and in such a way that your answer
will be courteous as well as responsive. Since you are out of sympathy with
cats, you may quite properly give this as a reason for not appearing at the
dedication ceremonies of a cat hospital. But bear in mind that your opinion
of cats was not sought, only your services as a speaker. Try to keep things
straight.
