#13795: Setting HEADER_IMAGE to empty string causes Firefox to crash

 Severity:  normal        |    Keywords:  custom header
--------------------------+-------------------------------------------------
 Using define('HEADER_IMAGE', '') causes Firefox (XP/3.6.3) to hang on the
 Appearance/Header page initially without fully completing the page
 download. Returning to that page after accessing another Admin option is
 impossible and Firefox has to be killed via a commandline switch.

 The issue can be replicated in TwentyTen by changing:


 {{{
 define( 'HEADER_IMAGE', '%s/images/headers/path.jpg' );
 }}}


 to:


 {{{
 define( 'HEADER_IMAGE', '' );
 }}}


 and also by simply commenting out the HEADER_IMAGE define. IE8/XP manages
 to remain stable but does display a js error on the second load of
 Appearance/Header.

 Using nightly build: 3.0215172[[BR]]

 Confirmed by second user using 3.0-RC2[[BR]]

 Mass plugin deactivation had no effect.
