invalid Windows EFI entries in GRUB

Bug description:
64bits computer with pre-installed EFI Windows 7. (remark: same bug if
Windows8)
Installed Ubuntu 64bits in dual-boot. GRUB (grub-efi) is correctly
installed and allows to boot Ubuntu, but it does not allow to boot
Windows.
Its menu shows 2 INVALID Windows entries. When selecting these
entries, it displays "Invalid EFI file path" error, and returns to
GRUB menu.
It appears that GRUB creates BIOS/mbr entries when it should be
UEFI/gpt type entries.
*********************** WORKAROUND **************************
either boot Windows from the (EFI) BIOS menu, or add valid Windows entries via Boot-Repair.
