Version:           3.3.89 (using KDE 3.3.89 (CVS >= 20041129), compiled sources)

OS:                Linux (i686) release 2.6.7

I've seen some bugs already closed which explain this problem, but it's still here in current CVS.
Here is how I can almost always reproduce it by browsing my local Qt online help:
I view (in the second of three open tabs, if that matters)
/opt/qt3/doc/html/qlistview.html#setSorting
Now I click on the link which is on the word "SortOrder" from the method QListView::sortOrder () const

The new link in the Location bar is
/opt/qt3/doc/html/qt.html#SortOrder-enum
but the new page most of the time simply shows the top.
When I click into the Location bar and press Enter, konqi scrolls to the correct position.
