Hmm... I am using 454 and it is defaulting to Portrait mode on .epubs for me. I am reading exclusively with Koreader now and have no ebooks being managed by Kobo's Nickel. I saw the History selection in the Home Menu it looks to be the same as the Recent Reading selection. I also read .pdb ebook files with Koreader but haven't gotten around to one since I did the nightly last night.
I am not trying to be much of a tester, just a user. I am in an .epub right now I could check if it is an issue going from portrait to Landscape and back. Here goes ... gone to landscape , no problem until I tried to swipe backwards, forward was no problem. On the backward swipe it rebooted. Selecting the Koreader.png got me to my File Manager page and using History I am back in the .epub in portrait mode (Not on the right page though). All my bottom menu setting have been reset to their defaults, so I have to do that again. I can't get Go To Page or location to work for me. Well, I can't get out of the Go to menu, so I'll have to poweroff.
