Recent contacts can't work normally after period of time.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Customize some source code (but dont change recentContacts plugin), build 
and run in Qt
2. recent contacts in local different from recent contacts sent from server
3. before connecting, show recent contacts Ok (get from local), when connected, 
it changed into new list (wrong list for a long time ago)

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
Vacuum 1.3.0.2230 Alpha, Window 7

What version of the Qt are you using?
Qt 4.8.5

Please provide any additional information below.
I found that the recent contact list sent from server is very old. It seems 
that it couldn't update recent contacts in server when local updated. Local is 
always OK.

Recent contacts saves on the server every time you changing status to Offline, 
every time you connect to server recent contacts loaded from it. May be you 
terminate application before you changing status to Offline, in that case 
recent contacts will not be saved on server or your server was restored from 
backup with old contacts.
