A file with an .epub extension is extremely likely to be the zip+xml+html based, and extremely popular, e-book format rather than any form of INI configuration file. I cannot find any reference to .epub being a configuration file name for any system with a cursory search.
As it is listed directly after .ini in the data file, it was likely a copy/paste error.
The line should probably read as:
["", 0, ".epub", "application/epub+zip", "electronic book document"]
