Koreader failing to start

[doron]

When I turn on my Kobo Aura I get the KSM menu but when I click on the koreader option I see the message "opening <my current book>" but then nothing happen and I stay on the same menu. Btw Nickel loads Ok.
How can I fix this issue?

Does this happen with other books/documents? You may have to use Notepad++, (or another editor that handles Linux scripts properly) to change your defaults.lua entry:
KOBO_SCREEN_SAVER_LAST_BOOK = true, to false. So that you can get past where you are now. You have KOReader starting and trying to load a book, so it is not KSM or how the KOReader startup is set to work.

It would be helpful if you supplied the Version of KOReader that you are on and if there is something new that might need to be considered, any recent changes/updates/hacks?

I've done that but the koreader still tries to open this book and doesn't start (strange).
I use KSM 08 2015.10.27 (Is there a point to update it if it's possible?).
Before happened I read the book without any problems and I didn't change anything.

What does KOReader's crash log says (it should be located in koreader's main folder)?

That vaguely sounds like corrupted history or sidecar or settings, there's a couple of reports on GH with workarounds.

it says only: Segmentation fault

[Ken Maltby]

If you have a "defaults.persistent.lua" you need to change that as well.

KSM is not likely involved. Your KOReader version is in the "git-rev" file.

On start? That'd be new - and potentially interesting, see https://github.com/koreader/koreader/issues/1974

Save your full koreader folder before trying any fix, we may need it to replicate your issue.

[doron]

I don't have a "defaults.persistent.lua" .
As I've said this is KSM 08 2015.10.27, in the git-rev it appears as v2015.11-stable.

I've saved the folder (140M)
It's so large maybe b/c I've put the dict files twice because I didn't know where to put them, in
g:\.kobo\dict\ and in
g:\.kobo\koreader\data\dict\
Which is the wrong place?

[Ken Maltby]

If you are just reading the book, and don't have highlights or bookmarks you want to save, you could try deleting the book's "history" folder entry and any SDR folder for the book, as well as the book's file. After saving a copy of the book file, if that is your only one.

Only removing the book solved the problem. (and then I could add it and read it again)
You are simply great!!

Just one question - where should the dict files go -
in g:\.kobo\dict\ or in g:\.kobo\koreader\data\dict\ ?

[Ken Maltby]

The dict files or folders go in koreader\data\dict\ for KOReader. KOReader uses dictionary files in the Stardict format. The /.kobo/dict/ location is for the stock Kobo software, and they use their own dictionary format, as I understand it. I don't think the two are compatible.

I am still using KSM7.4 and have my koreader folder in /.adds/, I am not sure where KSM8 has it's files, and file references anymore.
