'grub-emu-lite' failed to start 'normal' mode (command 'normal' in module 'normal.mod')

'grub-emu-lite' failed to start 'normal' mode (command 'normal' in module 'normal.mod') due to missing license information in 'datetime.mod'.

Expected behavior:
Command 'grub-emu-lite -d /usr/lib/grub'
starts properly in terminal UI mode ('normal.mod' module)

Actual behavior:
Command 'grub-emu-lite -d /usr/lib/grub'
fail to start properly and starts only in "rescue mode" instead.

Command output:
$ grub-emu-lite -d /usr/lib/grub
error: incompatible license.
Entering rescue mode...
grub rescue> normal
Unknown command `normal'.

I suggest working a bit on the commit message and then git-send-email the patch to <email address hidden> so that it can be applied upstream, this is not something we should carry downstream.

Thanks for quick response!
I was not sure how should I propose patch to upstream.
I will post link to upstream bug when it will be created.
