You can run a visitor to get to the textures and turn this setting off.
You can either make your own, or use osgUtil::Optimizer::TextureVisitor
osg::Node* node = osgDB::readNodeFile(...);
osgUtil::Optimizer::TextureVisitor tv(true, false, false, false, false,
(the arguments to TextureVisitor's constructor are "changeAutoUnRef",
"valueAutoUnRef", and the rest all false so nothing else is changed.)

Strange, I tried it on Vista as well and I didn't have any problem. I
notice you're using the stable version of OSG (osg55 = OSG 2.8, the
current SVN trunk is at 62), so perhaps something was fixed that affects
this, and it would not crash for you in a more recent version.
Hope this helps,
