with binding_of_caller installed, errors in certain filetypes cause NoMethodError for nil:NilClass errors

[joshskeen]

for example, an error in a .scss file caused a undefined method `[]' for nil:NilClass error:

better_errors (0.0.7) lib/better_errors/error_frame.rb:7:in `block in from_exception'
better_errors (0.0.7) lib/better_errors/error_frame.rb:4:in `each'
better_errors (0.0.7) lib/better_errors/error_frame.rb:4:in `each_with_index'
better_errors (0.0.7) lib/better_errors/error_frame.rb:4:in `each'
better_errors (0.0.7) lib/better_errors/error_frame.rb:4:in `map'
better_errors (0.0.7) lib/better_errors/error_frame.rb:4:in `from_exception'
better_errors (0.0.7) lib/better_errors/error_page.rb:58:in `backtrace_frames'

changing line 6 of error_frame.rb to:

if BetterErrors.binding_of_caller_available? && exception.__better_errors_bindings_stack

avoids this, but i'm not sure if that's the best fix for the problem. It might be better if binding_of_caller were disabled altogether in this case.

I just upgraded and have replaced "undefined method `[]' for nil:NilClass error" with a beautiful, helpful screen showing me the problem. Frustration gone! Brilliant. Thanks!
