I think that most people are complaining because sooo maaany help files are missing.
It's just a general thing.
If it's just one for a specific application, then they can reinstall that application, sometimes it helps. ( which I do, but still no help file )
The complaint comes from announcements that the man pages and help files are cut out on the installation CDs to save space.
So, the complaint must be seen as a general thing, not one specific app.
It is said that reinstalling kdebase4 will partially help.
Many times, there just isn't one written yet.
So, what's a man to do
