[old problem]
The serialized-object class loader, when resolving its icons, tries to load the serialized object, and see if its class is executable or not. If there is an error deserializing, it displays an error n
ode, as it should. However, it also prints one of two (cryptic!) messages to standard output. Rather, it should display the error node, and also create a subnode describing the reason why it is in err
or, similar to the parse error node for SourceChildren atd.

[newer]
OK, so it no longer prints to stderr--it dsplays an exception, but the exception just gives the name of the object without explanation. The real error is still dumped to console. Bad UI.
