Why did you distort my message by snipping essential context?

The "this" I was talking about was the correct handling of category
properties in the new functions, not the distinction between an absent
property and a value of nil.

Let me put it to you again: you need to deal with category text
properties properly.  If you don't, the things I listed in the paragraph
above will surely happen.
