As far as I can see, the problem occurs only if the disk is MBR/MSDOS formatted and the installer is booted in the EFI mode. So we should create some test cases and test.

Test case 1:
Prerequisites:
 - one disk; partition table -> GPT
 - no EFI-System-Partition
 - The installer is booted in EFI mode => [ -d /sys/firmware/efi ] && echo UEFI || echo BIOS
Expected result:
 - Warning is printed about missing ESP, no crash

Test case 2:
Prerequisites:
 - one disk; partition table -> MBR/MSDOS
 - no EFI-System-Partition
 - The installer is booted in EFI mode => [ -d /sys/firmware/efi ] && echo UEFI || echo BIOS
Expected result:
 - Warning is printed about missing ESP, no crash

Test case 3:
Prerequisites:
 - one disk; partition table -> GPT
 - EFI-System-Partition exists
 - The installer is booted in EFI mode
Expected result:
 - Installation succeeds

Test case 4:
Prerequisites:
 - one disk; partition table -> MBR/MSDOS
 - EFI-System-Partition exists
 - The installer is booted in EFI mode
Expected result:
 - Installation succeeds

In my opinion, it is a bug in ubiquity, that it is not complaining about a missing ESP before the installation begins.
