Comment 9 for bug 1302930

I've got newest version from repository (update mentioned earlier is installed)

I know how to reproduce that now:
1) Use Facebook account
2) Open chat with someone
3) Write, close chat window
4) Wait for response, don't open notification yet
5) Reconnect network
6) Write Reply to message another way (by messenger on phone, or in browser
7) Wait for reply from another side
8) Now you have two or more notifications

I can check later which steps are obligatory if you need, but with this workflow it happens every time.
Also i see side effect that number of notifications on dock is wrong.
