Comment (by steevithak):

 I've picked up maintenance of a wordpress site that is experiencing this
 problem. The log fills with of these two errors

 PHP Warning:  next() expects parameter 1 to be array, boolean given in wp-
 includes/plugin.php on line 527, referer: wp-admin/admin.php?page
 =vimeography-edit-galleries

 PHP Warning:  current() expects parameter 1 to be array, boolean given in
 wp-includes/plugin.php on line 523, referer: wp-admin/admin.php?page
 =vimeography-edit-galleries

 Until this error message is triggered:

 PHP Fatal error:  Maximum execution time of 30 seconds exceeded in wp-
 includes/functions.php on line 0


 Adding "is_array()" in plugin.php seems to fix the immediate problem
 (wordpress dragging our server to halt and filling the error logs) but I
 could use some help tracking down the indirect problem of what code in the
 plugin is causing the problem, so I can file a bug report with the plugin
 author. Am I correct that what I should be looking for is plugin code
 referencing the $wp_filter variable? If so, any pointers to docs on what
 the plugin *should* be doing with that variable to avoid causing wordpress
 to enter an infinite loop?
