warnings during update

When updating the module the following warnings showed up:

• warning: array_merge() [function.array-merge]: Argument #2 is not an array in /.../update.php on line 309.
• warning: Invalid argument supplied for foreach() in /.../update.php on line 542.

Everything seems to be running fine, not sure if any update steps were skipped.

Using PHP Version 5.2.4.

This is the table structure after the update:

CREATE TABLE taxonomy_redirect (
  vid int(10) unsigned NOT NULL default '0',
  module varchar(255) NOT NULL default '',
  path text NOT NULL,
  tid int(10) unsigned default NULL,
  separator_replace varchar(1) default '',
  remove_text varchar(250) default NULL,
  filter int(4) default '1',
  KEY vid (vid)
);

Is that correct?
