There are a few things that goes wrong here, but you could send me your
code and i will have a look at it. Or you change your app to work with
gtk+2.0 the Tree and list functions are now a lot easier to handle and
adding pictures or widgets is simpler than in gtk+1.2 i think in long
term it was better to choose gtk+2.0 for this task.
