#13554: multiple empty messages when receiving image
------------------------+---------------------------------------------------
 Reporter:  tomkiewicz  |     Owner:  bartosz
     Type:  patch       |    Status:  new    
Component:  Gadu-Gadu   |   Version:  2.7.11 
 Keywords:  images      |  
------------------------+---------------------------------------------------
 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 (because pidgin doesn't support sending
 images via gg), login with one gg account
  2. run Pidgin 2.7.11 under linux, 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.
