With a clean install, the steps to reproduce this problem are:
1 - change the owner of the page PageGroupTest/Four from CarstenKlapp to
another user
2 - view the page - will correctly show the new owner
3 - view PhpWikiAdministration/Chown - it will still show Carsten as the
owner.

I have traced this problem through the call stack to WikiDB_Page->getOwner()
and WikiDB_Page->get() -  get() does not find a value for 'owner' in the
metadata of the page and it falls back to 'author_id', staring from the
first available version of the page.

As Reini suggested, it does appear that this is related to caching - when
the page is actually being displayed, all of the data is correct. However,
when the page is referred to indirectly (via lib/plugin/WikiAdminChown.php,
lib/plugin/WikiAdminSelect.php and lib/PageList.php in this case), the
cached data is incorrect or incomplete.

So far, I have been working around the periphery. I do not really know how
all of this works, so it may take me a while before I find anything. Given
that Reini are working on the caching, is it worth me investigating further?
