Right, googling this, this is a common error on dreamboxes. It doesn't like foregroundcolor on a progress bar, but you need to use a graphic for the progress bar instead of a colour..
The problem is no one has been reporting this as an error, even on dreamboxes. So why are you getting this error.
As you are using openatv due you have the setting "crash on skin error" set to yes. This is a stupid default that openatv tend to set on new image install
