This looks like the same issue as #42.

Suggested fix seems to have worked for me, thank you.

Yes, this fixes my report in #42, a diff:

This worked for me when changing...

- @styles            = options[:styles]
+ @styles           = options[:styles].clone

But I received an error with the clone on the processor.
