minimagick: UndefinedConversionError on ruby 2.0.0-p594 & p598

When I do:

MiniMagick::Image.read(source_content)

I get the following error:

     Failure/Error: subject.run
     Encoding::UndefinedConversionError:
       "\x87" from ASCII-8BIT to UTF-8

I met this issue and found that only files under 10kb were affected. This fix: http://stackoverflow.com/questions/10496874/why-does-openuri-treat-files-under-10kb-in-size-as-stringio saved my day and resolved this issue.
