 Replying to [comment:60 obenland]:
 > @alexvorn2 Could you test with [attachment:39693.2.diff] and see if you
 can still replicate #40177?

 I get some warnings after theme install:


 {{{
 Warning: array_merge() expects at least 1 parameter, 0 given in
 D:\Dropbox\htdocs\wordpresslastmu\wp-includes\widgets.php on line 1149

 Warning: array_diff(): Argument #2 is not an array in
 D:\Dropbox\htdocs\wordpresslastmu\wp-includes\widgets.php on line 1150

 Warning: Invalid argument supplied for foreach() in
