Oauth 2 and QTCPServer issue

[HellFighter]

I'm using QT lib https://github.com/pipacs/o2 for authorization using Oauth 2.0. For example i can try to authorize in facebook using example provided in there. If I use GrantFlow AuthorizationCode everything works fine, but if i switch to GrantFlowImplicit authorization fails. After research I found that in void O2ReplyServer::onBytesReady() method when it read data from socket I've got empty query string!
@GET / HTTP/1.1
Host: 127.0.0.1:1965
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,/;q=0.8

Accept-Language: ru-RU,ru;q=0.8,en-US;q=0.6,en;q=0.4@
But when I look in my browser I can clearly see a access_token and so on after #.

How can I receive data placed after #?

I'm using Qt 5.4 beta on Mac OS X

I can describe the problem in the abstract of the library used. When a local QTCPServer handles redirect from the social network with URI like this:
@http://127.0.0.1:1965/?#access_token=CAADPRS5aPeABAPGqlEILMSdRlNMGBK0wUU38GmWTWrTPwV39j5ToNaOKoTlKVJBs2icOKesdKQOEgYF8JAWcWnZASOs8ZAdyNfpbKRq9VVI7HtFrYBAfyBikpqqk6KjsvZBFcdjxBZAAymGKj0OwTyjtKHRNsgTKcqSLZCnHWt3gGuGZBWWKKFBjeZAfzZBOH9Q91GXLEbpnZCIFU5y1qtIoE&expires_in=5160500@
(I can see it in my browser), after reading all received data from soket
@socket->readAll();@

there is no query string at all:
@GET / HTTP/1.1
Host: 127.0.0.1:1965
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,/;q=0.8
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.122 Safari/537.36
Accept-Encoding: gzip,deflate,sdch
Accept-Language: ru-RU,ru;q=0.8,en-US;q=0.6,en;q=0.4@
The question is: why browser shows me /?#access_token=CAA... but QTCPServer shows only / ?
