TypeError: 'c' is not a constructor in Opera

I'm getting this error on Opera, with 0.8.0 (and dunno if there was same error with older versions)

Timeout thread: delay 4 ms
Uncaught exception: TypeError: 'c' is not a constructor

Unfortunately, Opera fallback to JSONP and JSONP polling doesn't work at all, and I don't know why.

Internet Explorer is affected too (and I suppose all browsers with Flash sockets), but fallbacks to XHR and data exchange is working.

This issue should be moved to https://github.com/LearnBoost/socket.io-client.

Ok, I open new issue there.
