I'm using 7.x-1.x-dev together with Views 7.x-3.x-dev.
When I create a view showing teasers of a content type, for which I have a Content Template, I get the error mentioned in the title for each result. The error refers to line 932 in the contemplate.module file.
This occurs when the View is configured in such a way that the 'Display Links' option is disabled.
This seems logical when looking at the code :
$vars['content'] = array(
'body' => $vars['content']['body'],
'links' => $vars['content']['links'],
I figured that if links display is disabled in the view settings, $vars['content']['links'] would be empty at this stage.
Changing line 932 to the following code, solved things for me.
'links' => (isset($vars['content']['links']) ? $vars['content']['links'] : FALSE ),
Feel free to correct my code there, as I might not be using best-practice coding standards.
I should also read up on how to create a patch. Promise I'll do so. In the meanwhile, maybe someone else can patch / commit this.
