@qlob: Hopefully, it keeps using the last valid cover (or a blank page, if that happened to be the first book opened after a *fresh* install)
In the same vein (like the K5 version), periodicals (newspapers/magazines) are skipped
To expand a bit on my answer to your previous questions, here's the list of disabled modules in the Python build:
PYTHON_DISABLE_MODULES="dbm _bsddb gdbm readline _sqlite3 _tkinter _curses _curses_panel"
So, nearly everything, including ssl, except for curses, db & sqlite. I can probably add sqlite if someone needs it. (curses too, although it's a bit of a PITA, it depends on ncursew, which isn't bundled on the Kindle, and I don't currently build).
@knc1: Mwahahah! I remember those warnings on some of my good old US pbooks
