An easy way to reproduce it is to do a quick ff/rew while the mp3 file
is being loaded from disk. Your change guarantees that the mpeg thread
gets one extra iteration before the wps updates but it doesn't guarantee
that the ff/rew will occur during that iteration. The solution would be
to not update the wps until the ff/rew completes in the mpeg thread but
that's kinda messy and probably not worth it for such a minor issue.
