Описание
When the webdriver for the Browser object downloads data from a HTTP server, the data pointer is set to NULL and is allocated only in curl_write_cb when receiving data. If the server's response is an empty document, then wd->data in the code below will remain NULL and an attempt to read from it will result in a crash.
