I kinda guessed it was :-D
Just wondered if foo.mp3 was a test file included for such purposes. Turns out
it's not.

Here's the output with an actual file:

I hope that helps at all.
I tried playing the same file in Amarok and the progress bar worked SOMETIMES.
I click stop, wait a few seconds and click play, and I repeated the process
about 10 times.
About 40% of the time it works as expected.
About 60% of the time it EITHER plays for the first 3 seconds without a
progress bar, but then fixes itself (the bar suddenly appears correctly after 3
seconds) OR the progress bar doesn't function at all until the track is stopped
and started again.
