Oops, missed that. I do see that you have parented the drawer to the
KCategorizedView though.
As a wild guess - try not parenting the KCategoryDrawer instances to
their respective views - I can't recall exactly but there might have
been a problem with doing that as otherwise I wouldn't have deleted it
by hand in the IconMode code in System Settings.
