Yes, originally kst used its own internal dirfile reader (from which the
getdata library was created).

The desktop you are using should not matter.  You make it sound like if
you remove the kst-getdata plugin that kst 1.8 will still read your
dirfile data (albeit incorrectly), which is weird.  

Do you have both kst 1.8 and 2.0 installed at the same time?  How did
you install kst 2.0?  What version of getdata do you have installed?
