android.content.res.Resources$NotFoundException when trying to get a drawable image

i searched the web and this site in particular, but i haven't found an answer to my problem yet.

My aim: I have a ListView with some elements, one is an ImageButton. I want to set the Image of this Button dynamically, based on data i have stored in the local SQLite Database.

Here are the code snippets:

Saving the Drawable Image in the database:

e.setBild(R.drawable.goal_icon);

as you can see, i save it as an integer. From what i've read, that's the way to go.

Using the Image:

I think the more important part is, how i try to get the Drawable Image. This is the part of my Adapter i use to fill the ListView:

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    if (convertView == null) {
        LayoutInflater mInflater = (LayoutInflater)
                getContext().getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = mInflater.inflate(R.layout.list_item_actions, null);
    }

    ImageButton icon = (ImageButton) convertView.findViewById(R.id.icon);
    try{
        icon.setImageResource(getItem(position).getBild());
    }catch(Exception e){
        icon.setImageResource(R.drawable.default_icon);

    }

The 'getBild' method gets an integer (obviously).

He allways goes to catch and gives me the default_icon. Here is the Stacktrace:
