Isolated it to the startup script just as your response came in...
commenting that line stops the crash.
Tried researching python-dbus stuff...
Added this to startup:
OUT = open("/tmp/CMdbus",'w')
OUT.write("dbus_interface=%s\n" % dbus_interface)
dbus_interface=<dbus.service.BusName org.ClawsMail.PythonPlugin on
<dbus._dbus.SessionBus (session) at 0x31f6e30> at 0x3250210>
but you knew that... :)
So, assuming startup ends, I'm still looking for how to pass the dbus
info to a shutdown script in a way to issue a close()...
BTW, any objections to adding this line to the examples as first line?:
# -*- Mode: python; -*-
It tells emacs to load python-mode since the files don't end in .py
