Works fine here.  Quote from debug log:

...
2013/05/07 16:12:53 [debug] 36830#0: *1 http request line: "GET /gw_proxy/test%2btest/ HTTP/1.1"
...
2013/05/07 16:12:53 [debug] 36830#0: *1 test location: "/gw_proxy"
2013/05/07 16:12:53 [debug] 36830#0: *1 using configuration "/gw_proxy"
...
2013/05/07 16:12:53 [debug] 36830#0: *1 http proxy header:
"GET /gw_proxy/test%2btest/ HTTP/1.1
Content-Length: 0
...

That is, request line sent to a backend is identical to one got 
from a client.

You may want to check if you have problems on client and/or 
backend instead.  In any case, looking into nginx debug log might 
be helpful.
