fixed a badly formed exception logging that would cause uncaught exceptions in AEViewer view loop for EventFilters that threw excpetions with null cause. This uncaught excpetion caused all kinds of headaches debugging badly behaving filters because the stack trace would not be printed!  This fix should help a lot to reduce uncaught exceptions and make debugging much easier.
