Hi there,

I'm having a nasty bug and just spent an hour tracking it down.

I'm using `erc-desktop-notifications' to get IRC messages sent with my
nickname over D-Bus using `notifications-notify'. This function calls
`dbus-call-method' which contains the following snippet at the end:

    (with-timeout ((if timeout (/ timeout 1000.0) 25))
      (while (eq (gethash key dbus-return-values-table :ignore) :ignore)
	(let ((event (let (unread-command-events) (read-event nil nil 0.1))))
	  (when (and event (not (ignore-errors (dbus-check-event event))))
	    (setq unread-command-events
		  (append unread-command-events (list event)))))))

This `read-event' call causes me trouble. Basically what happens, is
that it changes the ERC buffer in a very subtle way so that the last
line is then on top. Basically, the buffer is supposed to be shown as:

/-----
| <jd> ohla
| <foo> hey
| <foo> how are you jd?
| [#bar]
\-----

But because of this `read-event' call, the buffer is "recentered to the
top" and I finally see this instead:

/-----
| <foo> how are you jd?
| [#bar]
|
| 
\-----

Which is utterly inconvenient. I've tried adding `save-excursion' around
(read-event), but that doesn't change anything. I wonder what this
function can do that changes the buffer, and in any way, that doesn't
look like an expected and right side effect.

Hint?
