Probably neither. The bugs are not known to me using 1.3.10 Alpha
(CVS HEAD) on Ubuntu, but as we repeatedly stress on this list, if you
obtain a build from your Linux repository, the repository provides
that build, not us.
If you provide an example recording clip posted to YouTube or similar,
and give us the exact parameters you are using for Normalize and Noise
Removal, I'll try it out, but I would not expect to find a problem. Also
from your description (if a much smaller normalisation has still
amplified the waveform), it sounds as if you may have the recording
setup at too low a level.
