[Mediawiki-l] uncorrect subst behaviour when inside <includeonly>

Hello

I am using :

* MediaWiki: 1.11.0 * PHP: 5.1.3RC4-dev (cgi-fcgi) * MySQL: 5.0.67

I have a problem with the mixture of <includeonly> and subst in a Template :

"Template:S" looks like : <includeonly>{{subst:A page template}}</includeonly>

and "Template:A page template" looks like This is the content of a page template

when, after saving, I edit again "Template:S" it now contains :

<includeonly>This is the content of a page template</includeonly>

The subst has been done, as if <includeonly> has no effect.

This uncorrect behaviour appears and disappears, I do not know why, there may be some conflict with extensions ?

Could someone help me to understand this very annoying phenomenon ?

The wiki is http://comprendrelactualite.free.fr/mediawiki/index.php so, you can look at what is implemented in.
