There was a recent commit made that should fix this:
http://developer.pidgin.im/viewmtn/revision/info/1d533cebad7c0dbda8ec8ebee1334d27dcae5f9c

Changelog:
Only check for EAGAIN if read returned less than 0. This fixes a bug
where the recv callback function would get called continuously if the
server closed our connection and errno happened to be set to EAGAIN.
