Hi all,
     I just took a look at the bug
and started working on it. I just have came down to the core of the problem
but I am stuck there. Here is the problem and I want some help from you guys
to fix it. Kindly help me.

In kdeedu/step/step.worldmodel.cc, in the method QVariant
WorldModel::data(const QModelIndex &index, int role) const which is an
implementation of the QAbstractItemModel class's data() method, the index
passed is valid, i.e isValid() returns true but the internalPointer() is
null. I am just wondering if this possible at all. i.e how can index be
valid when it points to no data. But some one on #kde-edu told its
definitely possible, but I did not understand how.
This exactly is causing the bug reported in the above link. Can any one help
me on how to go about to fix this bug?

Thanks and regards,
