 It looks like the stack trace is getting cut off for some reason...

 Maybe try this instead:

 Edit your `wp-config.php` file and find the `WP_DEBUG` line and change it
 to this:

 {{{
 define( 'WP_DEBUG', true );
 }}}

 Also add the following line:

 {{{
 define( 'WP_DEBUG_LOG', true );
 }}}

 Then visit the customizer again.  This should have the effect of creating
 a file named `wp-content/debug.log` containing the information needed to
 find the cause of the issue (it may show that a plugin is triggering
 this).

 Note: this configuration is not really recommended for production
 environments so I recommend changing it back as soon as you are done
 (i.e., set `WP_DEBUG` back to `false` and remove the `WP_DEBUG_LOG` line).
