AppleDoc Categories not showing in quickhelp

I've succesfully generated a docset with AppleDoc by following the installation instructions. If i got into XCode Documentation Organiser, everything is there, including the categories:

But when I ⌥-click on one of my category methods I see nothing but this:

I've tried a lot of things but none of these work:

• Adding --no-merge-categories
• Adding --merge-categories
• Changing filename extensions
• Restart XCode
• Restart macbook
• Search google (AppleDoc quickhelp categories)
• Search stackoverflow
• Search gitHub repository issue list (https://github.com/tomaz/appledoc)

Please help, because I want to generate documentation, and most of my library consists of categories. I'm using the latest AppleDoc (appledoc 2.1 (build 858)), and Xcode 4.6.3.

Edit: are there users actually using AppleDoc? Does the quick help actually work for you? I also note a lack of documentation even though the repository is updated regularly.

It seems nobody else is using appledoc but me. Anyway, it looks like it is a bug in XCode, i have pushed a workaround in github. Comment if you want details.
