Shield.io .png occasionally isnt created correctly

[JonathanReid]

Sometimes, but not everytime, the .png created from shield.io is corrupt and un openable. I can see the shield .png before its applied to my icons and they can not be opened by my mac.

I get the following output:
`/Library/Ruby/Gems/2.0.0/gems/mini_magick-4.5.1/lib/mini_magick/image.rb:204:in rescue in validate!': �

This seems to happen for no clear reason, and I can run just the command over and over and see different results each time.

I debugged it a while ago. Seems like shields.io's server gives an error page ("please try again..." instead of a valid png from time to time. After installing librsvg the error doesn't occur anymore because badge now requests svgs which seem to be more stable.

[JonathanReid]

yep, installing librsvg has fixed the issue, Badge is now a lot more stable.

Thanks!
