Ah ha, 
Another interesting experiment doing the round trip from osg to ive and back.
e.g.
osgconv -O noTexturesInIVEFile cow.osg cow.ive
osgconv cow.ive cow2.osg

cow2.osg has the same problem and cow.ive, and on comparison on cow.osg and 
cow2.osg I noticed the image definition has grown an 
"unRefImageDataAfterApply TRUE"

I get the same texture problem when I load cow2.osg, and it behaves normally 
again when I set the 'unRefImageDataAfterApply' flag to false.

So my guess is that the image data may getting released before the other viewer 
instance has finished with it?
