When default skin is changed it appears mixed with monobook skin. Digging in to
the code I realized that the cache was not invalidated when a new skin was
loaded. This is the case when a user loads a skin and because of that this
problem is not observed.

In the file includes/User.php from line 294 you can read

		unset( $this->mSkin );
		$this->mDataLoaded = false;
		$this->mBlockedby = -1; # Unset
		$this->setToken(); # Random
		$this->mHash = false;

and I changed to 

		unset( $this->mSkin );
		$this->invalidateCache(); # VEB
		$this->mDataLoaded = false;
		$this->mBlockedby = -1; # Unset
		$this->setToken(); # Random
		$this->mHash = false;

VEB.
