Details on version and operating system

Checked with the latest development build (copy version output from About dialog)

• [X] I made a backup of my libraries before testing the latest development version.
• [X] I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. Start JabRef
2. Drag a PDF file onto the main table
3. Get the exception

Note: Dropping onto the entry editor works
