Thanks for following up on this.  So the fix I installed avoided the
backtrace, but it didn't lead to the behavior you want, i.e. the one
promised by `ibuffer-default-shrink-to-minimum-size'.

>From reading the code it seems here that the intention is that
`ibuffer-default-shrink-to-minimum-size' should only work when
`ibuffer-auto-mode' is also enabled?  But that is not documented, is it?

Does anyone know how any of this is actually supposed to work?
