Bug Description

The Next button on the Terminal (chroot) page is initially available. When this button is clicked, the spinner appears for a few seconds, as expected.

Sometimes, after the spinner stops, the Options page does not appear, and the Next button is grayed-out and can no longer be clicked. (The Back and Quit buttons are still active).

This was observed in Ubuntu 14.04, but further analysis indicates it may also occur in other releases as well.

WORK-AROUND:

A work around may be to...

1)
On the Terminal page, click the Back button.

2)
Then select the "Continue customizing the existing project" radio button.

3)
Then click Next, and the Options page is displayed.

The function create_installed_packages_list() must be invoked before exit_chroot_environment() because exiting the chroot environment kills all processes using the custom squashfs directory. In some cases, the process for create_installed_packages_list() gets killed when it is invoked immediately after exit_chroot_environment().

This scenario only occurs when transitioning from the Terminal page to the Options page. This scenario does not apply when transitioning from the New Project page or the Existing Project page to the Options page.
