Calibre 3.14 error adding epub book

[dhdurgee]

I am encountering the following attempting to add an epub book to calibre:

calibre, version 3.14.0
ERROR: Cannot add books: Failed to add some books, click "Show details" for more information.

Worker process crashed while executing job
Traceback (most recent call last):
File "site-packages/calibre/utils/ipc/pool.py", line 107, in recv
File "site-packages/calibre/utils/ipc/__init__.py", line 22, in eintr_retry_call
EOFError

System is Linux Mint 18.3 x64 running on Lenovo IdeaPAD z560 with 8G of RAM. Let me know what else you need to get this working properly. I have addd epub books before, but it has been a while and there have been several updates since then.

Seeing the above I updated to the latest DeDRM plugin, v6.5.5, and the problem is gone.

Thank you for the pointer to debugging this.
