Outlook 2010 crashing while reading e-mails

I have a user that is using Outlook 2010.  It is crashing when they read e-mails.  I have 11 other users using the same configuration (other than their ids, etc..).   Outlook does work ok if we start in safe mode.

I believe it is an ADD-IN causing the error based on the error description below.  

I am not sure how identify and remove the add-in causing the problem OR if the root cause is something else.

Configuration Info: Windows XP SP3; Outlook 2010 using IMAP e-mail.
