Exception when merging entries

[j0hannes]

JabRef version 5.0-dev on Arch

• I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

And exception occurs when merging entries.

Steps to reproduce the behavior:

1. mark two entries
2. select merge from context menu
3. make choice and click "Merge entries"

Exception
