Comment(by NPetr):

 Hello, I can confirm this issue. And maybe it has relationship with
 http://developer.pidgin.im/ticket/7204. In the debug log it says:
 "offlinemsg: Account "kermit4@…/Pidgin" supports offline messages" as
 kermit reported. But facebook does not support offline messaging in spite
 of it uses XMPP. Workaround is send a message through right click from
 buddylist - Buddy Pounce > send message when contact is online.

 I guess that the patch of offlinemsg.c fix the issue. I can't code in C
 but the PHP idea is:

 {{{
 if (purple_account_supports_offline_message(account, buddy))
 {
   $findme = '@chat.facebook.com';
   $pos = strpos($mystring, $findme);
   if ($pos === false) {
     echo "The string '$findme' was not found in the string '$mystring'";
     purple_debug_info("offlinemsg", "Account \"%s\" supports offline
 messages.\n",
                       purple_account_get_username(account));
     return;
   } else {
     echo "The string '$findme' was found in the string '$mystring'";
     echo " and exists at position $pos";
   }
 }
 }}}

 How it will be written in C language code?
