If you are running accross this error
[BUG] cross-thread violation of rb_gc()
ruby 1.8.6 (2008-08-11) [universal-darwin9.0]
- say you are are installing the latest so-called “stable” typo version on your OSX machine – then you might see the above error. Here is the solution: *remove the bundled json gem!*: It is version 1.1.3, which is way old, and apparently it contains some binaries that were compiled using ruby 1.8.6. Just install the “json” gem locally.

Wow, after banging my head on this for a day, your post helped me out. I have Rails 2.3.4 and ruby 1.8.7 – but no JSON gem was installed. I simply installed the gem and now I can use rails again. sudo gem install json
Thanks!
Thank you. This is what happened to me too.. and after I found nothing on the Web I decided to at least put that small note onto my blog and let google do the rest.
