Unable to send the message, the conversation couldn't be started

[Scott & Ramona Worden, Timber Lake Creations]

 Hello,

I'd like to use Pidgin for messaging on a home/business network using Bonjour.  One PC is Win 7 and two are Win XP.  They all see each other in the Buddy List and the two XP PC's can communicate, but the Win 7 one displays this message after attempting to send a message "Unable to send the message, the conversation couldn't be started".

Thank in advanced for any help you can provide.  Attached is the debug log.

Scott
