Koreader crashes every few pages and i have to wait a few seconds for it to show agai

[beautylov]

Hello everyone, good afternoon.

I recently jailbroke my Kindle and I’m trying to use KOReader. However, I’ve noticed that it crashes quite often. After reading a certain number of pages, KOReader freezes and closes, and I have to wait a few seconds before it shows up in my Kindle library again.

I was advised to check the crash log, but I don’t really know how to interpret it.

Could I have installed something incorrectly? Is there anything I can do to fix this issue?

Here is the most recent log below.

It's a scroll... It's a codex... It's KOReader!

Try the latest nightly (OTA release on Github). There are more than 200 changes so far, no idea if it fixes that already

Just download the package and overwrite koreader folder. Settings will be preserved
