Steps to reproduce 1> Create a new category. 2> add code to the category, including brackets, inside nowiki brackets to another category and save. 3> Try to add the category to the page. Actual Results: Fails to add. If you are using programs like Twinkle it will state the category already exists. Expected Results: Add the category in the approrpirate section outside nowiki brackets. Build: Current beta build. Not sure which version that is.
This is a bug in Twinkle, not a bug in MediaWiki. It should be reported to Twinkle's maintainer.
