They should; the PNG is telling the viewer that the pixels are completely transparent. If the tool(s) involved don't use the alpha channel they shouldn't write one; if a particular file doesn't need transparency the tool should write "fully opaque". (Sounds like a minor bug in the tool. :(
On the plus side, now I know a way to get rid of alpha channels in PNGs.
