Viewfield error on updating to latest version

When I updated the module from 1.x.1.0.1. to 1.x.1.0.2, the system started logging this error:

Notice: Undefined index: show_title in viewfield_field_formatter_view() (line 208 of /public_html/uhub/modules/viewfield/viewfield.module).  

I'm using it with views that build lists of comments and nodes created by specific users to display them on those users' profile pages.  The error doesn't seem to disrupt the display of those views on the profile pages, but the error log quickly became full of them, at least until I switched back to 1.0.1.

The offending line in the module is:

'#show_title' => $item['show_title'],

But, alas, I'm no coder, so would welcome any suggestions what I should do or where I should look (I did check, and the views I built both do have titles as fields).

Thanks!
