did you solve this problem? Does the problem still exist with the latest
PulseAudio in Debian Lenny? Probably yes according to the changelog [1]
there were no related changes.

Could you please also test the backported version [2]? You wrote you did
not have those problem with the version in Debian Sid/unstable back
then.

If the bug is still present, could you please test the latest upstream
version 0.9.21 and this does not help open a ticket upstream [3]. You
seem to know OProfile so you can probably find the reason with
upstream’s help.

Thanks,

Paul
