STEPS TO REPRODUCE
1.  Run krfb
2. Change unattended password
3. Try to save - oh, wait - there's NO SAVE BUTTON
4. Check ~/.config/krfbrc and see that it didn't bother to save your password

I'm ranking this as major. Without this, it is, in real life, impossible to use krfb for remote access. Every time it starts or every time KDE restarts, the password is changed. So you have to have someone at the computer when krfb is started so set it for that session. The whole purpose of krfb is remote access, but that is lost when someone has to be there to enter a new password every time krfb is run or KDE starts. If my system reboots at work, I cannot access it remotely until I go into work (or have someone else go) and set the password, since it's not saved.

OBSERVED RESULT
The unattended password is not saved

EXPECTED RESULT
The unattended password should be saved in ~/.config/krfbrc
