Comment(by v.plessky):

 Tested Kopete running on Linux, machine connected via Wireless connection.

 See Log file - Pidgin/Windows - talking to Kopete/Linux (wireless machine)

 As you  see, problem is not related to network.
 Kopete connects to Pidgin, and has 192.168.1.51 IP address (correct)

 BUT: Message from one client to another not displayed.
 It seems it's kind of format mismatch.
 Hope you will understand better from the log.

 Therefor, we need to debug network part of Pidgin code, to understand why
 it doesn't work in Wireless connection.

 ***
 I also added one more test user  - 'acer' (on wired computer)
 When I was trying to select it and do some action, Pidgin crashed.


 {{{

 (19:15:11) g_log: purple_find_prpl: assertion `id != NULL' failed

 Can you pls also look at this problem, or I need to file another bug
 report?
