Noisy plugins when exporting

Binary package hint: swh-plugins

swh-plugins_0.4.15-0.1ubuntu1_i386.deb in hardy are not working properly, when exporting in ardour they create the exported sound file with a vast array of noise. I removed them and tested with Feisty's swh-plugins_0.4.14-1.1_i386.deb which I previously used with no problems before upgrading to Hardy, and now also get this horrible noise with exported files with those plugins. I got from debian the "latest stable" swh-plugins_0.4.13-1_i386.deb and it all works well now. To test you can create a track, add a multiband eq (Steve Harris) and when playing will sound good, but when exported you will ge a noisy clip.

Thanks.
