Datenbank update endet mit einem java.lang.nullpointerexception

Kann mir jemand beantworten wieso diese anweisungen in einem absturz enden?

public void updateScoutlog(long id,String title,String content,String image){

    ContentValues values = new ContentValues();
    values.put(DbHelper.COLUMN_TITLE, title);
    values.put(DbHelper.COLUMN_CONTENT, content);
    values.put(DbHelper.COLUMN_IMAGE, image);

    Log.d("SCOUTLOGTitle", title);
    Log.d("SCOUTLOGContent", content);
    Log.d("SCOUTLOGImage", image);
    Log.d("SCOUTLOGId", String.valueOf(id));


  database.update(DbHelper.TABLE, values, DbHelper.COLUMN_ID + "=" + id, null);

}

Der Logcat spuckt das aus:

Ich gib die werte ja auch einzeln im logcat aus dort steht überall was drin.

Database.update........

die werte sind alle gefühlt. Der datensatz existiert in der datenbank.

Wenn ich das richtig aus den logs sehe ist database == null aber wieso ist das so?
