Bug 389759

patch to fix this issue

The Start/Stop action doesn't update text when clicked.

When `setText` method is initially called through the class constructor, it also sets `IconText` property. Now, further calls to `setText` doesn't change `IconText` property and hence the "start" / "stop" text changes are not reflected in the UI.

Here is a snippet from the doc.

> If the icon text is not explicitly set, the action's normal text will be used > for the icon text.

> If the text is not explicitly set in the constructor, or by using setText(), > the action's description icon text will be used as text. There is no default > text.
