 Hi,

 I used Pidgin for years and this had never happened before...
 But today it suddenly stopped normal operation and every my attempt to
 send a message to a buddy over ICQ results in red error message something
 like "Can't send message, not logged in" in conversation window (I'm on
 Russian locale so don't know correct english message)
 NOTHING happend to system or network, or whatever, everything is the same,
 but today it just doesn't work.
 Tried to uninstall it, clear Program files, AppData, registry, install
 latest version from the site - it's the same. At the moment I can't use
 Pidgin at all - it just receives the messages, but can't send it.
 - System - Windows 7 x64 (russian locale)
 - Pidgin - latest 2.10.7
 - No plugins, or extenstion, etc
 - No changes to the OS, or any part of the system, or any part of the
 network, it just suddenly stopped working

 Tried to run it in debug mode here is the error message from log:

 (12:04:42) gtkconv: setting active conversation on toolbar 057A4620
 (12:04:45) oscar: Sending IM, charset=0x0000, length=33
 (12:04:45) oscar: rate change (param ID 0x0001): curavg = 4838, maxavg =

 (12:04:45) oscar: Message error with bn 316613546 and reason 4 and errcode

 I have also attached this logfile to the ticket.
