+++ This bug was initially created as a clone of Bug #1191418 +++

Description of problem:

When migrating (export then import) config channels from an old 2.2 installation on RHEL6 to a new 2.3/nightly installation on RHEL7 config channels that contain a directory cannot be imported again.

Example use of spacecmd:

spacecmd {SSM:0}> configchannel_import db-postgresql-wal-el7.json
INFO: Importing config channel  Database PostgreSQL WAL EL7
INFO: Found file /var/lib/pgsql/data/postgresql.conf for cc Database PostgreSQL WAL EL7
INFO: Found directory /var/lib/pgsql/data/wal-archive for cc Database PostgreSQL WAL EL7

How reproducible:

Always

Steps to Reproduce:
1. Export config channel that includes a directory on SW 2.2 using spacecmd
2. Import the same config channel again in SW 2.3 using spacecmd 

Actual results:

Config channel is only imported in parts, directory import fails and spacecmd aborts import. 

Expected results:

Config channel is successfully imported

Additional info:

Sample config-channel export is attached.

Thank you  Patrick for the report. I really managed to reproduce the
problem and have prepared fix. In the meantime (as a workaround) you
can remove

  "content": ""

from directories in exports you plan to import. Either manually or
programmatically. Here is simple example:

import json
import sys

items = json.load(sys.stdin)
for item in items:
    for file in item.get('files', []):
        if file.get('type') == 'directory' and 'contents' in file:
            del file['contents']
json.dump(items, sys.stdout, indent=4)

Once again, thank you :-).

Changes should get into nightly soon.
