update.php urecoverable error when no updates available

Drupal 6.6 with some modules (cck, views, workflow, fields for cck, super Nav, ...), I uninstalled all, except "DHTML Menus" and "Module Filter". I saw some problem with "batch" jobs (workflow) when I ran "rebuild permission", it stopped the "progress bar" with error. Now it worked.

But NOW, with only 2 modules (DHTML and Module filter): I Run update.php, with NO UPDATES AVAILABLE.

And always the same error:

* warning: array_pop() [function.array-pop]: The argument should be an array in C:\Documents and Settings\Administrador\Mis documentos\PROYECTO\htdocs\drupal\update.php on line 315.
* warning: Cannot modify header information - headers already sent by (output started at C:\Documents and Settings\Administrador\Mis documentos\PROYECTO\htdocs\drupal\includes\bootstrap.inc:1151) in C:\Documents and Settings\Administrador\Mis documentos\PROYECTO\htdocs\drupal\includes\common.inc on line 141.

The update process was aborted prematurely while running update # in .module. All errors have been logged. You may need to check the watchdog database table manually.

¿How is it possible?

I write this because I wanted to upgrade modules (CCK 2.0), but it doesn't work. I tried to install any old module, and then upgrade it, but the same problem. I tried with NO UPDATES AVAILABLE, and the same error.

I will install a clean Drupal, but I would know what is happening, if is possible.

I can post extended error message, if needed.

More error message:
