Quick and dirty fix ...

$this->m_semdata = array(); //ADD

//save new page
        $newpage = SMWDataValueFactory::newTypeIDValue( '_wpg' );
        $newpage->setValues( $newtitle->getDBkey(), $newtitle->getNamespace(),
$pageid );
        $semdata1 = $this->getSemanticData( $newpage );
        $this->_update($semdata1);

$this->m_semdata = array(); //ADD

        // Save the old page
        $oldpage = SMWDataValueFactory::newTypeIDValue( '_wpg' );
        $oldpage->setValues( $oldtitle->getDBkey(), $oldtitle->getNamespace(),
$redirid );
        $semdata2 = $this->getSemanticData( $oldpage );
        $this->_update( $semdata2);

I do not yet understand what the problem is. What is "$this" in the above code?

I assume you are talking about changing the title of a page by moving it. When you do this, there will be a redirect from the old title to the new title. SMW follows redirects when querying for semantic data. This is a feature that helps to avoid information being lost when the title of a page changes.

But you can switch this behaviour off by using the configuration option smwgEqualitySupport (http://semantic-mediawiki.org/wiki/Help:Configuration#smwgQEqualitySupport). But the data that you get for a page that is a redirect is not very interesting anyway. It just says that it is a redirect to the new title.

>The data that you get for a page that is a redirect is not very interesting
anyway... 

except recording the triplets in another database.

If the name/URI are different the triplets are different (only put owl:sameAs for the old URI and copy the triplets with the new uri).

>This is a feature that helps to avoid information being lost when the title of a page changes.

May be there is another tool with the exact replica of the data when I m in my class like the class Rapstore ?

I still have significant problems understanding you, sorry. Could you provide a somewhat more verbose description of your problem? Here are some questions that you may want to address to clarify things:

* What are you trying to do?

* Is there some SMW function that does not work as documented?

* Is this problem visible to users of SMW? Can it be reproduced on sandbox.semantic-mediawiki.org?

* What is "$this" in your code snippet?

* You talk about "another database". How does this relate to your question? What is your database setup?

* You talk about "another tool" with "replica of the data". What data do you mean? What kind of tools are you talking about?

* What does RAPStore have to do with all this? Is your problem related to (RDF) storage bindings?

* What does RAPStore 
OK... it's a class in your project.
http://semantic-mediawiki.org/doc/SMW__RAPStore2_8php-source.html

* What are you trying to do?
I'm developing a new connector for SMW with the triplestore 4store
http://www.mediawiki.org/wiki/Extension:LinkedWiki

* Is there some SMW function that does not work as documented?
I didn't find the documentation but I use the template SMW_RAPStore2.php.

* Is this problem visible to users of SMW? Can it be reproduced on
sandbox.semantic-mediawiki.org?
The lambda user doesn't see this problem.

* What is "$this" in your code snippet?
it's the class 
http://github.com/BorderCloud/LinkedWiki/blob/master/class/SMW_LinkedWikiStore.php
and this class extends SMWSQLStore2

* You talk about "another database". How does this relate to your question?
What is your database setup?
Like Rapstore I duplicate the triplets in another database to create an endpoint sparql.

* You talk about "another tool" with "replica of the data". What data do you
mean? What kind of tools are you talking about?
I need to record the triplets in a wiki page in real time. So I need to call an function of SMW to give me the triplets current for one page (in the turtle format without prefix).
My dream is a function like this :
getExportTurtle(Title $title) => string (format turtle without prefix)

I found a hack for the moment but it will be for the next version.
