Bug#841051: cause indeed is empty $pkgdatadir and machine still boots

[Martin Steigerwald]

Hi!

First off, machine still boots with old config, so until I want to install new 
kernel, no problem.

Second: It indeed is empty pkgdatadir. I added

export pkgdatadir=/usr/lib/grub

to /etc/grub.d/00_header

and then it runs this script, but fails on the next one with the same issue.

Thanks,
