My `cap deploy:migrate` has suddenly stopped working, with an error:

```
*** [err :: 1.2.3.4:2222] bash: -c: line 1: syntax error: unexpected end of file command finished in 559ms
failed: "/usr/local/bin/rvm-shell 'ruby-1.9.2-p0@gemset' -c 'cd /home/user/app/releases/20111122182205 && #<Capistrano::Configuration::Namespaces::Namespace:0xa6a0cc> RAILS_ENV=staging  db:migrate'" on 1.2.3.4:2222

```

Obviously the error has something to do with this not being a valid command ... `#<Capistrano::Configuration::Namespaces::Namespace:0xa6a0cc>`

But I have no idea what changed recently that could cause it. Any ideas?

**update**

I know nothing of my code changed, but I may have fiddled with environments. I'm wondering if it could be due to different gemsets and versions of capistrano. It appears like different versions exist between with and without bundle exec calls.
