[News.eclipse.technology.mylar] Re: Upgrade causes error

[Mik Kersten <beatmik@xxxxxxx>]

Please note that the 2.0.0.v20070403-1300 build was made available on 
regular update sites yesterday afternoon.  The explanation is in my 
response to the "Mylar 2.0M2 is now available" post, eh.

Thanks go to Jörg for helping us with the tricky process of tracking 
this one down.  It required an incorrectly-formed task activity history 
(e.g. due to VM being killed) and the Task List is now more defensive to 
such errors so that it does not fail to start.
