Comment 0 for bug 1793056

Version-Release number of selected component (if applicable):
Tested with:
- libguestfs 1.36.13 (Ubuntu 18.04)
- tar v1.29 (Ubuntu 18.04)

How reproducible: 100%

Steps to Reproduce:
1. # virt-builder debian-8 -o deb8.img --no-network
2. # mkdir ~/deb8fs
3. # virt-copy-out -a deb8.img / ~/deb8fs

Actual results:

libguestfs: error: file receive cancelled by daemon
libguestfs: error: tar subprocess failed: tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

See attached debug.txt log that was produced by using "export LIBGUESTFS_DEBUG=1 and LIBGUESTFS_TRACE=1" before running

**Note**

I have downloaded 1.39.9 from github/libguestfs and this version works without an error in my build directory.

It appears that the actual problem is not with "virt-copy-out" specifically, but with the 'guestfish' which it relies on.

Running this on 1.36.13 (Ubuntu) fails:

# guestfish
><fs> add-drive deb8.img
><fs> run
><fs> tar-out / - | tar tf -
libguestfs: error: file receive cancelled by daemon
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

Whereas running the above on guestfish 1.39.9 from git does not produce that error.
