Changelog: 

When somebody sends me an image, I get some (depends on image size) empty
messages. It's about one empty message for every 2kB of image.

Steps to reproduce:
  1. install and run AQQ on Windows (or any other gadu-gadu client with image
     sending support), login with one gg account
  2. run Pidgin 2.7.11 under linux (maybe on Windows too), login with another gg
     account
  3. send ~50kB image from AQQ to Pidgin
  4. you should get 20-30 received empty messages in Pidgin and one with image
     after it

I fixed it by checking if gg message is empty and - if true - drops the message
and print warning in debug window.

Fixes #13554.
