After the upgrade from 4.0.2 to 4.0.3 I am unable to create new pages from a WIKI link. If I create a link in WIKI markup language, e.g. [[this is a link]] and I save this link and click on it, I receive a message that the page doesn't exist yet. When I click on the button to create it, I receive this error.

I am sure this worked correctly with 4.0.2.

Situation: Vibe 4.0.3 on SLES11SP4 behind NAM 4.3.

Anyone seen this error?
