I use Calibre with Linux (Ubuntu, and Mint). Often, my books end up with a forward slash as the first letter of the book's name - not in the metadata, but in exported books.

I get books from the library in a couple of ways, both of which exhibit this symptom. I connect to the content server from my Android reader, Moon+ Reader, or I export books to a USB-attached Kindle reader.

This can cause a problem if I want to find information on the book from the app, as the book will not be found unless I am able to edit the name to delete the forward slash.

FWIW, I have a duplicate library on Dropbox that i use to connect from my Android devices using Calibre Companion, and it doesn't seem to have this problem.

Has anyone had this problem? If so, did you solve it?

EDIT: I found the source of this problem (see post at end). It was caused by having installed, then uninstalled the DeDRM plugin.
