Bug 51837 [Progress] Bad message in progress dialog
I20040210 I got a bogus message when running a pile of jobs. A progress dialog appeared that read: "The operation cannot proceed because it is blocked by a background" A background what? :)
bundles/org.eclipse.jface/src/org/eclipse/jface/dialogs/Dialog.java
Shell shell = parent.getShell();
			if (shell != null) {
				shell.setDefaultButton(button);
			}
		}
		buttons.put(new Integer(id), button);
		setButtonLayoutData(button);
		return button;
	}

		layout.numColumns = 0;
