Setting invalid instance variable name

[dewski]

Using Ruby 1.9.3p0:

➜  ~  irb              
irb(main):001:0> require 'swish'
=> true
irb(main):002:0> Dribbble::Player.find 'garrett'
NameError: `@content-type' is not allowed as an instance variable name

Looks like it's due to Dribbble returning 500 errors. Not sure if this would be an appropriate response for that though.

Thanks for the report. We should definitely raise a less misleading error. I'll talk to @jeremyw and we'll see what we can do.

I'm seeing this again. Any ideas on a fix?
