Cannot launch rename operation from terminal only

[xpelican]

From what I understand, Metamorphose is supposed to be able to be run from the CLI interface without ever seeing the GUI, is this correct?

I used the GUI to create myself some config files for later reference over the CLI, but whenever I launch metamorphose with the -c and -p arguments at the same time, it crashes.

Example:
metamorphose2 -p=/root/Desktop/Test_Folder -c=/root/Desktop/test_configuration.cfg -a=3

This is the output I get:

Auto mode level set: 3
Traceback (most recent call last):

I have no idea if this is due to something I'm doing wrong, or where exactly a potential bug could be. Any ideas?

For reference, this is the content of my config file, test_configuration.cfg:

Overall I love Metamorphose and would love to see it grow, it's exactly the kind of program I needed, so major kudos for making it. Please help us help make this thing even better :)
