Undefined index: thumbnailURL in template_preprocess_gigya_user_profile()

This error is being returned multiple times when viewing a user who has linked social media accounts:

Notice: Undefined index: thumbnailURL in template_preprocess_gigya_user_profile() (line 1250 of /home/sites/udclients.co.uk/public_html/chambernetworks/sites/all/modules/gigya/gigya.module).

Judging by the debug user info, it seems to be happening each time a social media site / Gigya returns empty on the thumbnail URL because the error is repeated 4 times in this particular instance (http://udclients.co.uk/chambernetworks/member/webmaster) and there are four occasions in the debug info where there is nothing for 'thumbnailURL SUBvalue'.

Is there a patch that I need or am I missing something in my config?
