Upgrade to dev version solves inline problem but gives rise to other issues

I have followed the advice at http://drupal.org/node/1061576 and updated to dev version to get inline fields working. They do now work - thank you.

However I now have multiple notices and warnings:

• Notice: Undefined index: additional fields in date_field_views_data_alter() (line 252 of......modules\date\date_views\date_views.module).
• Warning: array_merge() [function.array-merge]: Argument #1 is not an array in date_field_views_data_alter() (line 252 of ........modules\date\date_views\date_views.module).
• Notice: Undefined index: field_name in _date_views_fields() (line 62 of.....modules\date\date_views\includes\date_views_fields.inc).
• Notice: Undefined index: field_name in _date_views_fields() (line 62 of.....modules\date\date_views\includes\date_views_fields.inc).

I'm not a programmer, just a user I'm afraid. But I think I've traced these back to a calendar view which uses a cck user-defined date field. (A very slightly modified version of the default calendar view i.e. I've not made changes other than to define the correct date field). The cck date field is no longer available as an option to choose from in the argument configuration options. Only node dates and user dates are listed to choose from.

Any thoughts from someone more able than me?
