uninitialized constant Thin::HttpParser (NameError)

This is the error I’m getting since I updated Thin from version 1.2.7 to 1.2.8. When I uninstall the newer version and tell my bundle to use 1.2.7 again everything is fine.

Get 1.2.10

I had the same problem with 1.2.9. The release was broken. 1.2.10 was fixed this afternoon and works like a charm (the developer fixed in minutes!).
