Incompatibility between PathAuto & Save as Draft modules under Drupal 6.24?

Hi, I just updated one of my sites from D 6.22 > 6.24. Everything seems to have gone smoothly except for 3 PathAuto-related warning messages that have started popping up any time I add *any* content, whether it's a blog entry, story with tags or even a basic page without any tagging:

•	warning: Illegal offset type in isset or empty in /var/www/vhosts/XXX/httpdocs/sites/all/modules/pathauto/pathauto.inc on line 91.

•	warning: strip_tags() expects parameter 1 to be string, array given in /var/www/vhosts/XXX/httpdocs/sites/all/modules/pathauto/pathauto.inc on line 96.

•	warning: Illegal offset type in /var/www/vhosts/XXX/httpdocs/sites/all/modules/pathauto/pathauto.inc on line 176.

I've found a few similar problems listed here in the pathauto issues, but they seem to relate to older (4.x/5.x) versions of Drupal, and none are quite the same.

I'm using Pathauto 6.16 and Token 6.18.

In addition, I also received the following error upon completing the update from D 6.22 > 6.24:

user warning: Table 'save_as_draft' already exists query: CREATE TABLE save_as_draft ( `nid` INT unsigned NOT NULL, `save_as_draft` INT NOT NULL DEFAULT 0 ) /*!40100 DEFAULT CHARACTER SET utf8 */ in /var/www/vhosts/mhsmi.org/httpdocs/includes/database.inc on line 551.

After some trial and error (ie, disabling EVERY third-party module *except* Token and Pathauto, then re-enabling them a few at a time), I've narrowed down the problem to some sort of incompatibility between Pathauto and Save as Draft...but the warnings only started appearing upon my update from Drupal 6.22 to 6.24.

I obviously haven't *solved* the problem yet, however, so I'm presenting it here in the hopes that someone can help with a solution (I've posted a similar thread on the Pathauto issues).

Any help appreciated!
