You need to call this before accessing the widget in the class "ui" points to.
Try moving this to the first line of the constructor.

This usually means that the application crashed. If you run in debug mode this 
should result in a backtrace, a list of function calls showing what the 
application was doing at the point of crash, usually including file name and 
line number of the code that triggered the crash.

P.S.: I'd recommend to not cross-post to that many lists, some people discard 
such messages without looking, effectively reducing the chance of getting an 
answer.

If you are working on something KDE Edu this list is just fine. Alternatively 
any KDE related development question is always welcome on kde-devel
