From Martin Naylor, "I have been experiencing a crash in the example osgtexture2D.

Browse Source 
Not sure why my system seems to be so sensitive to these problems.

But attached is a fix which seems to stabilise the example.
Note: it only seems to crash intermittently when spinning the object with
your mouse.

So I assume this is a threading issue because of the data variance missing
in some of the text node setups in the example.
