merge contact

Hi everyone, 

One of my team mates are trying to merge contacts. She has permission to "CRUD" but gets the error of:

We couldn't merge these cases.dupcheck.dc3ContactTrigger: execution of AfterDelete caused by: System.NullPointerException: Attempt to de-reference a null object (dupcheck).

Any suggestions on how to resolve this? Thank you in advance,
Cheers,
SW

The error message indicates there is an issue on After Delete trigger on Contact object.
It seems your org has Duplicate Check app installed. (https://appexchange.salesforce.com/listingDetail?listingId=a0N300000058vzKEAQ)
Since you can not read the trigger code for managed package, you may have to contact their support team to understand why your collegue is having such issue.
