I setup an konsole profile which has 'Command Name' Section like this

/bin/bash -c 'su - username'

It works when I change it, but after I exit konsole and opens it again, it becomes

/bin/bash -c su - username

which will cause some trouble. And I have to apply it again to make it work. So I guess there is some thing wrong while saving the ' or " stuff into the profile.
