I can confirm this lockup on startup (similar to the lockup on Mac OS X)
It's unrelated to the shown model. I used "osgcamera -2 -c cow.osg" for
my testing.
Hardware: Pentium 4, Geforce 6600, Windows XP, one screen.
I don't have any light to shed on this, but an extra data point,
osgcamera -2 -c cow.osg
Works fine on my Athlon64 X2 with 2 x Geforce 7800GT. App starts and
exits cleanly.
doesn't work here on a MacBookPro with ATI1600, Windows XP, single monitor.

If I understand the threading mechanism of
CullThreadPerCameraDrawThreadPerContext then I should see 13 threads
working, 1 main thread, 6 cull threads and 6 draw-threads. So one
cull-thread is missing, is this correct?
