Fatal error on adding module

I got this when trying to add the module:

Fatal error: Cannot redeclare simplenews_uninstall() (previously declared in /home/.inventor/bjornbjorn/drupal-sites/sites/all/modules/simplenews/simplenews.install:205) in /home/.inventor/bjornbjorn/drupal-sites/sites/all/modules/simplenews_analytics/simplenews_analytics.install on line 25

I had to delete the module from my modules dir to get my site running again.
