It could very well be that just in this race the technology was not working on Webbers car (as would be no surprise with new techology). Just wondering because of: https://news.ycombinator.com/item?id=6532428
Guess who's had the most issues with KERS in the last two years? Mark Webber.
Red Bull haven't been able to get either the weight distribution or something else right on his car to even get 'normal' KERS working reliably.
Yes, what was not right was the car being in flames because a crash :P
