Pagify Plugin

Sorry I missed your post.

Carlos, I think that disable the display of canonical links - is a bad idea, if you use "Fancy URLs".
When the "Fancy URLs" is enabled, the same page will be available with different URL. For example:
...
If not specified in header canonical link, and search engine suddenly somehow "know" about such links - the site may be penalized for spamdexing (in this case - for different pages with the same content).

I don't think you are going to be penalized for this. See here:

So you're helping Google select your preferred url, but there's really no problem if you have duplicate pages in your site (it would not be the same if it was across different sites), Google will select one of them (which will normally be the one you have linked in your site) and ignore the rest.

However: if you have several pages with different content but sharing the same canonical link, all but one will probably be ignored by Google.
I've seen this happen with some site using GS.
