Renaming the class and Python file to something totally different makes it 
work properly. But if I change them to, say, KeywordsTree2 
(keywords_tree2.py) or Keywords (keywords.py) the same error persists. So 
something goes wrong in PyQt4.uic.loadUi() which makes it associate promoted 
widgets that are named something like Keyword.* with PyKDE4.kdeui. Seems 
weird, but I can't track down what goes wrong.

So, it all works again now, but if someone else stumbles into this problem, 
just rename your class and hope for the best. :)
