pulseeffects also is not from Debian. I installed it from a PPA ages ago but it crashed occasionally so forgot about it. However I recently realised upgrades had replaced all PulseAudio packages with ones from the PPA! It actually works better now, no crashes, but obviously is now a Frankendebian which can't properly be supported. This info may or may not be pertinent to your issue.
This is on a siduction system installed over 2 years ago and regularly upgraded.
