Notice: Undefined index: comment in antispam_comment_view() array_merge() [function.array-merge]: Argument #1 not an array

Drupal 7.2:

Notice: Undefined index: comment in antispam_comment_view() (line 1140 of ...sites/all/modules/antispam/antispam.module).
Warning: array_merge() [function.array-merge]: Argument #1 is not an array in antispam_comment_view() (line 1140 of ...sites/all/modules/antispam/antispam.module).

This is what I get as a logged in user if I want to add a comment and click on the "preview" button. Can't get past the error since there's no Ok button after this error.

If I set Preview as optional and click the save button instead I get this error:

Fatal error: Cannot use string offset as an array in…sites/all/modules/antispam/antispam.module on line 1014
