Foren / Cotonti / Bugs / Error in parsing BBcode

The problem occurs in Cotonti 0.9.3

While creating new page using MarkItUp text editor to add link we need to write (i don't know is this problem present while using CKEditor, but propably yes, couse i think it's bbcode's fault, not just a text editor):

[url=http://somesite.com]SomeSite's name[/url]

Instead of adding a link, it generates:

[url=<a href="">http://somesite.com]SomeSite</a>'s name[/url]

which is not a working link.

UPDATE:

Ahh sorry, i see that, it's known issue and problem occurs because of HTML Purifier
