While I was doing a custom installation I ran into this error and the
subiquity session terminated:
get_blockdev_sector_size: (log=4096, phys=4096)

Since this again points to sfdisk, I belief that it's related to this ticket.
I'm attaching entire /var/crash and /var/log and mark this as affecting
curtin, too.
