+**July 21 2008:** I update this bug report as it still seems to be an issue: E.g. when creating a subpage whose name contains
+a colon by inserting an appropriate wikilink in the parent page: the new page can be created using that link, but afterwards
+there won't be a link to this page. Like madduck said above it seems to be htmlscrubber removing this link. However everything
+works fine if the same page is being linked to from another subpage because in that case the resulting link starts with `../`.
+
+At the moment I see two possible solutions:
+
+1. let all relative links at least start with `./`. I haven't tested this.
+
+2. Escape the colon in page titles. I created the following patch which worked for me:
