Doesn't include pathauto.inc in some cases

_pathauto_include() is called before that execution, so I don't know how this could go wrong. Maybe you're missing the pathauto.inc file?

The code in question is:

      _pathauto_include();
      // Get the specific pattern or the default
      if (variable_get('language_content_type_'. $node->type, 0)) {
        $pattern = trim(variable_get('pathauto_node_'. $node->type .'_'. $node->language .'_pattern', FALSE));
      }
      if (empty($pattern)) {
        $pattern = trim(variable_get('pathauto_node_'. $node->type .'_pattern', FALSE));
        if (empty($pattern)) {
          $pattern = trim(variable_get('pathauto_node_pattern', FALSE));
        }
      }
      // Only do work if there's a pattern
      if ($pattern) {
        // Only create an alias if the checkbox was not provided or if the checkbox was provided and is checked
        if (!isset($node->pathauto_perform_alias) || $node->pathauto_perform_alias) {
          $placeholders = pathauto_get_placeholders('node', $node);
          $src = "node/$node->nid";
          $node->path = pathauto_create_alias('node', $op, $placeholders, $src, $node->nid, $node->type, $node->language);
        }
      }

We could potentially optimize a smidgen by moving the _pathauto_include() closer to the pathauto_get_placeholders, but I agree with Dave that it's hard to see how Pathauto is causing this.

Maybe some other module is using pathauto_get_placeholders?

I thought I was having a similar issue, but it turns out that I had updated to 6.x-2.0-alpha2 without realizing it.
Here's the error message I get when I try to edit a node:
"Fatal error: Call to undefined function pathauto_pattern_load_by_entity() in /.../sites/all/modules/pathauto/pathauto.inc on line 365"

I reinstalled 6.x-1.4 and everything works again.

So I suppose that could be an issue for 6.x-2.0-alpha2. Let me know if you'd like me to submit it as such.
I'm just happy that 1.4 is working.

@vidr - did you clear the cache after updating? My guess is that this is a menu/cache related issue.

Hi greggles,
I did clear the cache, a couple times in fact; I looked back at my install history in terminal and I found that I had updated the pathauto module to 6.x-2.0-alpha2 back on 8/19/10. Which is probably why I couldn't remember doing it.
I'm not sure why I wanted to update to an alpha install on a production site but I did.
I also installed 6.x-2.0-alpha2 on two other sites and they are working fine!

So I think the error was a result of conflict with some other module I installed recently.
Looking at the install history on the site in question; which wasn't showing that error last week, I had installed the latest version of webform_validation on 9-13 and linkchecker on 9-9.

So the error could have been as a result of a conflict with one of those.

Since no one else has been able to duplicate this and it seems like it has resolved itself, then I'm going to mark this as fixed.

pathauto.inc doesn't get included in my case, when i'm using dpm(pathauto_cleanstring(...)) in the php custom code block.

You can't just call the pathauto_cleanstring() function and expect it to work. You need to manually include the file otherwise you get an error:
module_load_include('inc', 'pathauto');

Also please use proper issue queue etiquette and do not re-open closed issues.
