Image just won't get uploaded/previewed with fbconnect module installed.

fbconnect will somehow destroy the headers and probably doesn use the shutdown function right. That problem is know, iam not going to look into this in detail

listed fbconnect on the incomp section.

This is my solution:

function hook_fbconnect_config_alter(&$config)
{
	// the fbconnect and wysiwyg_imageupload do not get along so this removes fbconnect footer additions
	if(arg(0) == 'wysiwyg_imageupload' && arg(1) == 'upload')
	{
		unset($config['api_key']);
		unset($config['secret_api_key']);
	}
	
}

I'm not sure about the if clause, but you get the idea

Did you place that in template.php or in the .module?

Thats a hook an cannot be placed within a theme. So he used a custom module

This has been isolated here:

it is fixed on my side, i cant do anything to fix this.

As mentioned here: http://drupal.org/node/893984#comment-3747964 - the error is with this module no fbconnect.
Here is a patch to fix it, just requires greater degree of specificity on the form selection.

The patch worked for us and resolved the Upload issue. Many thanks!

Any hopes in getting @larowlan's patch committed?

It's a fix that works well for me, apparently others on this thread and at http://drupal.org/node/893984#comment-3747964
