The problem was that just before fit-window-to-buffer was called in
`ibuffer-shrink-to-fit', the display was showing a split frame with
both windows displaying the same ERC buffer, even though the current
buffer was actually *Ibuffer*.  I added a (redisplay t) call to force
the display to be up-to-date before fit-window-to-buffer is called,
which fixes the problem.

Hi,
There is a bug when using conjointly these two features. Here are the
relevant portions of configuration :
;;make ibuffer resize itself to its buffer size
(setq ibuffer-use-other-window t)
(setq ibuffer-default-shrink-to-minimum-size t)

No specific configuration for erc, just enabling tracker is enough.
Then, run erc, and, in any erc buffer, call ibuffer. The screen briefly
flashes as an ERC window opens then disappears, and the ibuffer window is
reduced to a much smaller size than what it would be outside ERC. I think
the issue is erc's hook to window-configuration-change somehow messing with
ibuffer, but I'm not experienced enough to find where the bug is.
