Git commit ad149fa7b323b1e46c835dd91cd7c180c3ca3c45 by Marcel Wiesweg.
Committed on 28/08/2011 at 16:18.
Pushed by mwiesweg into branch 'master'.

Improve null-object handling in ImageTagPair and TagProperties.

When attempt is made to create an object with in invalid id, now
a null object is created and methods detect this properly, refusing to edit
the db with invalid parameters.
(shows that the SharedNull paradigm is not always so much more elegant than d =
0)
