Crashing on Non-UTF8 Character Encoding

I can't seem to reproduce this. Can you try with the latest psych gem? Make sure to do gem "psych" before requiring it.

You're right in that it doesn't happen on the current release of psych, 1.2.2 from what I can tell, but you need to declare the gem dependency or it won't happen.

If ActiveRecord listed psych as a dependency this would've been avoided because, presumably, it would have fetched the most recent version. The one bundled with Ruby 1.9.2-p290 is, sadly, broken. It has to be manually added in the Gemfile to fix this.

Ruby 1.9.3-p0 is bundled with Psych 1.2.1 which produces a slightly different error, but at least no hard crash:

The 1.2.2 version is fine in 1.9.3, though.

Thanks for the prompt reply. It would be great if the next build of 1.9.3 will have 1.2.2 or better bundled with it as this is probably going to hit more than a few unsuspecting people.
