rr invokes to_str on Pathname instance in the loadpath

[hedgehog]

This erro is thrown by rr, but mocha and rspec smeed not to have the trouble...

Another example: rr is infecting Psych when running from guard-minitest.

I don't have enough details from the OP to figure out what's going on there, but I just tried setting up guard-minitest on a new project under Ruby 1.9.3-p385 using RR 1.0.4 and am not seeing any error. Can you post the test that you are trying to run?
