Following a module update (ApacheSolr Biblio), I issued update.php. And I got this error:

• warning: reset() expects parameter 1 to be array, null given in /var/www/webdocs/afrixml/update.php on line 314.
• warning: array_pop() expects parameter 1 to be array, null given in /var/www/webdocs/afrixml/update.php on line 314.
The update process was aborted prematurely while running update # in .module. All errors have been logged. You may need to check the watchdog database table manually.

Yet, when I checked back into Admin pages, all checkmarks were green.

Just in case, here is a partial output of the Recent log entries:
