 The theme editor ('wp-admin/theme-editor.php') page showing a "Undefined
 variable: error" notice for a fresh installation.

 After checking the 'theme-editor.php' file, I found that the error
 variable used on line number 159 and 277 is not defined except on line
 number 153, where it is defined inside an 'if' conditional block.

 {{{#!php
 <?php
 if ( ! is_file( $file ) ) {
         $error = true;
 }
 }}}


 The variable should be initialized prior to line number 152:

 {{{#!php
 <?php
 $error = false;
 if ( ! is_file( $file ) ) {
         $error = true;
 }
 }}}

 To recreate the issue, please enable debug mode and visit 'wp-admin/theme-
 editor.php' page.
