Error while uninstalling the modules

I was uninstalling the modules (all the enabled modules), and I got the following error message:

user warning: Table 'drupal61.nodewords' doesn't exist query: DELETE FROM nodewords WHERE name IN ('abstract','canonical','copyright','description','keywords','revisit-after','robots') in /Library/WebServer/Documents/dr61/sites/all/modules/nodewords/nodewords_basic/nodewords_basic.install on line 34.

I am going to re-add the check on the table to all the uninstallation function of the modules implementing meta tags.
