Example plug-in to reproduce the problem with. Execute the sample command twice and check the Error Log.

Steps to reproduce:

1. Run the following code twice (replace plug-in ID):
	String logMessage = "some log message";
	IStatus errorStatus = new Status(IStatus.ERROR, Activator.PLUGIN_ID, logMessage + " child", null);
	Activator.getDefault().getLog().log(new Status(IStatus.ERROR, Activator.PLUGIN_ID, logMessage + " top", new CoreException(errorStatus)));
2. Observe the 2nd error log entry in the Error Log has 2 children, while only 1 is expected (the first error log entry is fine).

Example plug-in with command that logs an entry with the code above: "ExampleErrorLogDuplicateEntry.zip" (execute the command twice)

We assume this is coming from the fix for bug 567395.
