I don't like the default ~/Documents folder, so on my installs I always set 'System Administration -> Paths' (Document Paths:) to just /home/david. I've done that in tde, but then with every app I open (kate, kwrite, etc..) when I select 'open' it defaults to looking in the /home/david/Documents folder.
It looks like tde is ignoring the setting. Anybody else see this in the latest GIT builds?
Documents is part of the XDG standards. I don't care for that default location either. :)
Regardless, the location information is stored in $HOME/.config/user-dirs.dirs.
Check whether KControl is updating that file.
If not then edit user-dirs.dirs manually and restart the session. See how kdialog behaves after that.
Could be a bug in KControl.
