pgAdmin3 (wxwidget 3) crashes when clicking to modify any Login Role

[David Colmenares]

Whenever I double-click an element in the Properties tab (or an element under "Login Roles" in the object browser sidebar) I get this annoying message from the application and asking me to close it. However, I can continue using the application (and saves whatever I do to the DBMS), but if staying in the same "Login Roles" context, it will keep drop-in a pop-up with the assertion error message.
