warning qith quickpost and broken html page display

First off, congratulation for this extremely useful module. I truly believe user input *should* be extremely simple for a certain type of users, particularly senior ones as well as computer illiterate ones. And this module is great in that respect. I second the idea of having such *simple* way to enter data into the system in the drupal core. Also I've seen complex masks for entering data into drupal (pages, stories, etc.) for upcoming versions of the system, but we don't have to run into overly complex systems, only apparently "more simple" ... Enough words so far. Here is the problem I've found with your module:

warning: array_unique(): The argument should be an array in C:\Program Files\Apache Group\Apache2\htdocs\drupal\modules\quickpost\quickpost.module on line 189.

warning: Invalid argument supplied for foreach() in C:\Program Files\Apache Group\Apache2\htdocs\drupal\modules\quickpost\quickpost.module on line 193.

I'm calling the folowing url:
http://localhost/drupal/node/quickpost/page/13

(it is a page already existing).

Also what I see is a broken html page (I'm using the kubrick template with PHPtemplate engine).

Any ideads of what this problem is? A final not, I'm using the latest CVS version of quickpost.

Thanks!
