guestfish verbose output

Description of problem:
When -m option and --listen option is used at the same time, the appliance dies.

Version-Release number of selected component (if applicable):
guestfish-1.2.7-1.el6.5.x86_64
libguestfs-1.2.7-1.el6.5.x86_64

How reproducible:
Alway

Steps to Reproduce:
1. prepare test.img that contains a file system in /dev/sda1

2. run the following command,

$ LIBGUESTFS_DEBUG=1 guestfish -a test.img -m /dev/sda1 --listen

when the command completes executing, the pid of the process is printed,
save it in $pid.

3. do the following,

$ guestfish --remote=$pid -- ping-daemon

then this is printed on the screen,

send_to_daemon: 0x15ff3e0 g->state = 3, n = 28
child_cleanup: 0x15ff3e0: child process died
closing guestfs handle 0x15ff3e0 (state 0)

Actual results:
appliance died.

Expected results:
don't die
