Comment 8 for bug 1066144

Let me correct myself, I *did* just manage to reproduce it on amd64, but previously I thought when I tried, I did not see it show up on amd64, only on i386. Seems it is possible to reproduce it on amd64 after all.
First boot: bug
reboot: bug
sudo apt-get purge postfix (also removes bsd-mailx): no bug
sudo apt-get install postfix (bsd-mailx suggested, but not installed): bug
sudo apt-get purge postfix (and reboot of course): no bug

...
I can very reliably reproduce it when postfix is installed, and *not* reproduce it when postfix is removed.
Note that this is still in vbox, haven't had a chance to test on hardware yet due to lots of respins, but I haven't forgotten.
