[dataimport] backout 6947201033be (related to #2788402)
(and add a try: except to cache the intended error)
The problem actually comes from the ``MassiveObjectStore``
in the ``dataio`` cube, so it should be corrected there.
Here, we only protect it with a ``RuntimeWarning`` so that
the user can see the problem.
``value`` is set to ``None`` (whence to ``NULL`` from
a database standpoint), so that the data can be nevertheless
inserted in the database. However, only the keys present in
``row`` are actually non-'``NULL``'.
The real solution is to work out the issue in ``MassiveObjectStore``
directly.
The current try/except should only be a temporary hack.
Once you have read the `RQL tutorial`_ and you know the application'`schema`_,
you're ready to define your own views. Just type the RQL query retreiving data
you're interested in in the search field. If the view used to display them
doesn't fit your need, choose another one in the possible views box (this box
isn't displayed by default, but you can activate it in your `user
preferences`_). Once you're satified, add a `bookmark`_ if you want to reuse
this view later.

.. _`schema`: schema
.. _`user preferences`: myprefs
.. _`bookmark`: doc/bookmarks
Below are some example of what can be acheived...
