Is it me or can somebody explain why when I "setenv OSG_NOTIFY_LEVEL debug" and
then run osgstereomatch example and I'm seeing the following all these warnings
in the output (see below). It seems like things are running okay (maybe because
these are only warnings :-). I'm running with OSG 2.6 with the OSG Data Set
from OSG 2.6 but I don't think anything has changed in this area since then...
I don't get any messages when I run without the notify level.
I'm not sure what the intended action is in each of these cases but there seems
to be alot of warnings (in my opinion they should be errors).
