Performing the verification for Bionic:
First, reproducing the bug with the current version:
# apt policy rsync
rsync:
Installed: 3.1.2-2.1ubuntu1.1
Candidate: 3.1.2-2.1ubuntu1.1
Version table:

# mkdir -p a/1 b/1; echo "/1/2/3" > list
# rsync --dry-run --stats -Pav --delete-missing-args --files-from=list a b
file has vanished: "/root/a/1/2"
ABORTING due to invalid path from sender: 1/2/3
rsync error: protocol incompatibility (code 2) at generator.c(1271)
[generator=3.1.2]
Next, updating the package to the version available in -proposed,
clearing the directory, and making sure that the bug is fixed:
# apt policy rsync
rsync:
Installed: 3.1.2-2.1ubuntu1.2
Candidate: 3.1.2-2.1ubuntu1.2

As shown above, there is no longer a crash due to missing parent
folders. Therefore, the bug has been fixed for bionic and verification
is complete.
