Eftersom man inte kan skriva så mycket på twitter så fortsätter jag här.

när det finns ett syntax fel i någon fel så får jag ett http 500 fel men jag får ingen bra stacktrace så jag har inte en aning om vad som är fel. Det felet jag får är det nedan och det verkar vara nån konstig encoding fel om ställer till det.

Är detta något du har stött på tidigare eller har en aning om vad det kan vara?
Jag kör: Ruby 1.9.2-p290 med Rails 3.1.1, använder LESS och .erb som templates om det kan påverka.
