An interesting and odd thing about the Calibre User Manual. While you can read it just fine in Calibre itself, if you use Calibre to load it to a Kobo (at least the N647 "wi-fi" model) it causes the Kobo to crash. The device locks up while "processing new content" and can only be recovered by using a pin in the reset hole on the back. I tried this with two different N647 devices, one with the current firmware (1.9.11) and one with the older 1.9.8 firmware, and got the same results from both.

After this happens, the epub file is still present in the device and can be seen by Calibre or by a computer looking at the directory, but the Kobo simply pretends it doesn't exist.
