No, this is not a real Sinatra error :).
This is the personal homepage of Elad Meidar, a web developer and an entrepreneur specializing in Ruby on Rails. I hang around in Israel, and i am currently having the best time of my life over at Fiverr.com

I don’t think that there is something more annoying, disgusting, blood vessel popping in a web developer life, than browser testing.
Leave a side the already known rants, about IE being hell on desktop, and that nothing is working as you expect on all browsers, there’s also the issue of getting all these browsers to even get the test results.
To test on Safari, you need a Mac access (no, safari for windows is NOT a browser) and if you are working on a mac, you’ll need to dual boot windows or install a VM in order to get a convenient access to IE and it’s minions.
Well no more, Alkaline allows you to get a clean sweep access to 17 browsers, directly on your mac.
It sounds great, but the down side is that it’s not free and have a subscription licensing (per month, per day). it might be a cool idea and a nice initiative, but when BrowserShots.org is out there, it is much less attractive.
You're seeing this error because I think it is funny.
