Lead conversion error due to managed package

Our users are receiving the following error when attempting to convert a lead, and SF support has told us it is due to a managed package yet could not identify which. Does anyone have any insight into what package may be causing this, and how to resolve? 

'Error: System.DmlException: Insert failed. First exception on row 0; first error: FIELD_INTEGRITY_EXCEPTION, null: [] Class.leadconvert.BulkLeadConvert.handleRegularContactInserts: line 326, column 1 ' 

Any help is much appreciated.

Best,
Julian

Can you see the code behind? if not contact the app vendor
setup > App Setup > Develop > Apex Classes
look for the class named LeadConvert
if you can see the code (unlikely on a managed package) scroll down to line 326 and look what is done there.

another option could be that your users receive this error because your managed package is colliding with a dupe blocker or a lead / contact trigger

If support already told you that is due to a managed package I assume they logged into your org to review, then you only have the option to either de-install or contact the vendor
