Please fix the changelog to conform to the standard changelog style:

 - first describe the symptoms of the bug - how does a user notice? 

 - then describe how the code behaves today and how that is causing the bug

 - and then only describe how it's fixed.

The first item is the most important one - yet it's missing from this 
changelog.

Thanks,

	Ingo
