Ah, I think we may be at cross purposes. The problem I described is with Sigil v0.6.2 (Build time: 2012.12.06 20:35:42 UTC) not Sigil v0.6.0.2.
If I understood it correctly, meme's description in post #4, sounded as if v0.6.0 silently converted the nbsp entity to a standard space, which could be fairly disasterous with 'empty paragraphs'.
[Added: At least with v0.6.2 I can see when I have an epub with an 'nbsp problem' and can do something about it.]
