VLC adaptive plugin crash for some server

int HTTPConnection::parseReply()
...
    while(!line.empty() && line.compare("\r\n"))
    {
        size_t split = line.find_first_of(':');
        size_t value = split + 1;

        while(line.at(value) == ' ')
            value++;

        onHeader(line.substr(0, split), line.substr(value));
        line = readLine();
    }
...

When some server reply header has a key without value, there is a out of range exception at line.at(value).
