blocks any specialpage "Fatal error: Call to a member function on a non-object
in includes/SkinTemplate.php on line 306"

Happens every time I try to open any special page. So it's really a blocker bug.
I've tracked down to the functioncall $wgArticle->getID()

If you search teh web using google ("member function non-objekt SkinTemplate.php
line 306") you find several wikis that also have this problem.

In most cases it seems to be connected with a mediawiki-extension (e.g.
Blogextension) but in my case it is surely not as I disabled every extension in
LocalSettings.php. In some cases adding of $wgOut->setArticleRelated( false ) to
the extension.php helps but in my case I don't know where to add, as I don't use
any extension.

Perhaps there is a connection with editing of [[Mediawiki:Sidebar]] as it
occured the first time shortly after creating a new sidebar.
