There seems to be a bug which creates strange entries in the article
history. Please take a look at
http://de.wikipedia.org/w/wiki.phtml?title=Wikipedia:Ich_brauche_Hilfe&…
or
http://de.wikipedia.org/w/wiki.phtml?title=Benutzer_Diskussion:Kurt_Jansson…
There are entries created by "Benutzer:" or "Spezial:Contributions",
but
the users were logged in.
And BTW, the new edit§ion=new feature creates double entries if the
new text contains a heading.
