[WEIDU] WeiDu: ERROR: Invalid_argument("Filename.chop_extension")

I have been getting a weird bug suddenly in a component that I haven't touched and had been working for over a week.

The error I am getting is:

ERROR Installing [Core Revisions], rolling back to previous state
Unable to Unlink [TomeAndBlood/backup/0/OTHER.0]: Unix.Unix_error(1, "unlink", "TomeAndBlood/backup/0/OTHER.0")

I've attached my entire debug file, but the part of interest is posted above. Any ideas on what might be causing this?
