Using --rules_file flag causes an error

[jimdusseau]

Using the --rules_file flag will cause this error to be printed on the command line:

There was an error processing the command.
error: can't convert Symbol into Integer

This error is reproducible even when passing in the default rules file.

Example command:
paperless --rules_file=~/paperless.rules.yaml --simulate create ~/Desktop/AnyPDF.pdf

Running this same command without the --rules_file flag does not reproduce the issue.

Thanks. I will have a look into this as soon as I can.
