[protege-owl] problem loading galen.owl with protege 3 and protege 4

You have almost certainly run into an out-of-memory error.   
Unfortunately the logging in Protege 4 still has a bit of a problem  
and the exception is not always displayed.   If you can, increase the  
memory and let us know how it goes.

I believe that I fixed the problem with logging last night on an  
internal development branch (it will find its way to the head).
