I am using Mnemosyne version 2.2.1 on the Windows 7 operating system.
I have many duplicate cards in various tag-groups of my database and want to get rid of them.
Using "Find duplicates" selected from the "Cards" drop-down menu doesn't find any duplicates for me, but instead causes the following error message to appear:
An unexpected error has occurred.
Please forward the following info to the developers:
