Ok, I think that I found the way to reproduce correctly the error.
It arise when I try to view Diagram (with attributes) of a class that
is domain of a DatatypeProperty with enumerated range (i.e {"male" ,
"female"} ).
I was able to reproduce the error just using this simple owl:

==================================================================
This is a custom Person class with datatype property "gender"
declaring an enumerated range: {"male" , "female"}.
If you load this owl in TB 3.5 and try to open Person in the Diagram
with the "Shows attributes" checked it rises the excepion.
The same file in TB 3.4 work without problem.
As u said, is really concerning the user defined datatype....but how
could I make the same in another way resting compliant with OWL 1 (we
don't want to migrate to OWL 2).
Thankyou in advance for the support,
Busa.
