I get exactly the same errors / problems when trying to edit the Xubuntu 14.04 Live Iso on my Ubuntu 14.04 system.
Log is attached.

This assertion (see http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/glib2.0/trusty/view/head:/glib/gspawn.c#L1175) indeed fails when /dev/null cannot be opened while spawning a child process.

Both of your logfiles have the following error earlier (multiple times):

cannot create /dev/null: Permission denied

This seems to be a file system permission problem in the chroot.

Can you try the option "Do you want to customize the CD manually during building" and then "Run console application"? Then run the following command?

mount | grep "on /dev "

I'm having the same chroot file system permission problem when trying to create a custom Ubuntu 15.04 while using 15.04. Build.log attached.

This issue was fixed here: https://bugs.launchpad.net/uck/+bug/228235
When you start uck there's workaround mentioned on welcome screen:
...
Requirements:
1. about 5 GB of free disk space in /home/artem/tmp
(on local machine and mounted with "dev,suid,exec" options)
...
so it's crucial to remount filesystem where ~/tmp folder resides with "dev,suid,exec" options
(in my case it's a filesystem on a separate partition with mount point /home, maybe you have /home inside root filesystem)

you can do it this way:
sudo mount -o remount,dev,suid,exec /home
or if you have not separate partition for /home:
sudo mount -o remount,dev,suid,exec /

Then try "Run console application" one more time.
