I'm getting exactly the same problem updating Zen, though the versions are 6.x-1.0 and 6.x-1.1, respectively. I tried upgrading manually (replacing the zen theme directory with the new version), but I still got the same error message. Is there a workaround for this, like some way to reset Drush's database, so that I can upgrade it manually?

This seems to be caused by a block of information in the .info file for the Zen sub-theme.

; Information added by drupal.org packaging script on 2009-02-13
version = "6.x-1.0"
core = "6.x"
project = "zen"
datestamp = "1234555897"

If you delete that block, you won't get the error any more. Also, it seems that the new zen-6.x-1.1 STARTERKIT doesn't include that block any more, so it shouldn't be a problem going forward.

But I'm not trying to upgrade a subtheme. The problem is the Zen parent theme.

I too cannot upgrade following http://drupal.org/node/219527

Drupal just tells me the zen theme is out of date.

#2 has identified the reason this module update fails

Tip: you do need to delete that relevant block in the .info files for all sub themes, including zen and zen_classic

The problem mentioned in comment #2 has already been fixed for new sub-themes in Zen 6.x-1.1 and later. See #254821: Sub-theme's .info file triggers incorrect "out of date" flag in update module
