When attempting to access the kde-helpcentre function from all packages EXCEPT KOffice help is unavailable, although installed/present. Is it just a matter of setting the correct paths to these files, and if so, how? Attempting to access the help files in this way causes Konqueror to crash with what it describes as a software bug but I find this hard to believe if it is looking in the wrong place for documents to load.
This is fixed in the 7.0final preview directory.
