I can't replicate the problem -- but does the "SourceList::OnList"
procedure destroy the treeview widget by any chance?  If so,
you probably want to put a [break] in the binding script:

    bind $listname <Button-1> {
       SourceDialog::OnList [%W item [%W identify row %x %y] -text] ;
       break;
    }

Very few class binding scripts work properly if they're called
after the target widget has been destroyed...
