I've installed and configured module as it is stated in manual.
Here is my steps-to-reproduce:
0. Create content type called News
1. Go create new News item
2. add this to the content
[node:4, title="test"]
3. save page
4. after clicking save I've got my page with messages:
* News test has been updated.
* ignoring param 'title' for page as it is not valid. Possible values are ''.
warning: Parameter 1 to theme_link_node_thumbnail() expected to be a reference, value given in /var/www/includes/theme.inc on line 656.
No link is rendered also.

P.S.
The strange thing is that when I open up the page http://localhost/news/test (page that has been created in steps-to-reproduce) there are no complains/warning messages. But link to the node is still not rendered.

I've googled a bit and found some stuff with symptoms very closed to mine:

I've got the same problem.

At least now I know what module is causing the trouble (link_node) but I believe its related to something that changed in PHP. It works fine under Fedora Core 11 but on Fedora Core 12 I get a ton of warnings and no links. The warnings are the same as yours.

Well, here is my environment params:
Linux artem-laptop 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:27:30 UTC 2010 i686 GNU/Linux
info related to php is in attached 'php_test_results.html.tar.gz' file

NOTE:
To be honest I want to add that I've already had quite the same warning message with Drupal + node_symlinks. I've also googled that problem but with no luck. I've phased out 'node_symlinks' cause it wasn't vital for me. But now this module is.

OK, so it's something that altered in PHP, and it's only the edit page... ?

Does the change from http://drupal.org/node/772894#comment-2856752 work for you ?

Sorry for delayed answer!
Yes, proposed solution works for me. Thank you much for this hint! And a world shame onto PHP-dev-team! :)

The only problem I'm still having is warning message:
ignoring param 'title' for page as it is not valid. Possible values are ''.

I've noticed that after saving the line
[node:20,title="test_link"]
it transforms (somehow) automatically to the line
[node:20,title="test_link"]

Is that a reason of the problem?
Probably this quotes are escaped is because of installed WISYWIG CKEditor?

"ignoring param 'title' for page as it is not valid"
Did you follow the instructions in the README about "configure filters" tab of the same "Filtered HTML" filter ? If you did please open a new bug.

All, there will be a new -dev release shortly that also address' some RSS-feed issues.

I've just double checked and yes, you are right, I forgot to add 'title' into link_node filter. Please forgive my folly!
