Page will not validate with form in it unless I remove filters

I published the post and it still has validation errors. If I wrap the GF shortcode in that [raw] shortcode, the errors go away. Here is the post:

That page will have validation errors (I did not wrap the form shortcode in the [raw] shortcode. Here is the form output from the source:

<div class='gform_wrapper' id='gform_wrapper_3' >
<form method='post' enctype='multipart/form-data' id='gform_3' class='' action=''>
<div class='gform_heading'>
                            <span class='gform_description'>If you have a question which is not addressed here, please feel free to submit and we’ll get right back to you.</span>
                        </div>
<div class='gform_body'>
<input type='hidden' class='gform_hidden' name='is_submit_3' value='1'/>

<ul id='gform_fields_3' class='gform_fields top_label'>
<li id='field_3_1' class='gfield' ><label class='gfield_label' for='input_3_1'>Name<span class='gfield_required'>*</span></label>

<div class='ginput_container'><textarea name='input_3' id='input_3_3' class='textarea medium' tabindex='3'  rows='10' cols='50'></textarea></div>

</li>
</ul></div>
<div class='gform_footer top_label'>
<input type='submit' class='button' value='Submit' tabindex='4'/>
                        </div>
</p></form>

Not sure why there are closing P before the closing form and closing gform_wrapper div.

Yes, all on the same web host. Actually, different machines, same hosting company (1&1).

Could it be another plugin? Why would wpautop be running on the output from your plugin? (at least, that's what it seems like to me, since removing that filter removes the problem.)

This last site has the fewest number of plugins and is not really in use yet, so disabling all plugins here is not a problem. This is the first time I've used the Reptile framework, which made it seem even even weirder, since I just chalked it up to StudioPress themes in the past and it was easy enough to work around with using the [raw] shortcode.

Finally, this form happens to be really simple. Just three fields, no conditional logic.

The only other thing I do is always disable the visual editor for all my accounts. Not sure if that matters. I sent a login to this site using the contact form.

Created a test site with WP 2.9.2 and GF 1.3.10. I sent the login information and FTP login information using the support form.

Other things I thought of that were common to most of the forms I use.

1. I almost never use the form title but normally do use the form description
2. I almost never allow comments on posts

Let me know if you need anything else.

You can do whatever you want to that site (post, delete posts, pages, etc), it's not live in any meaningful way.

Thanks
