'Button rotation patch' makes KoReader crash

[denisuu]

Does anyone use KoReader with the 2-disable-hw-button-rotation.lua patch?

Since updating to version my Leaf 2 to 3.5.3 (7f5c78ff3), I've been experiencing crashes whenever I apply the patch and then press the volume up or down button, or swipe to go back.

I tried various versions of KoReader, but it might be a ROM issue, not a KoReader problem. I also tried factory resetting the device.
I expect it to be the case for other Onyx or Android devices too.

I know nothing about KOReader or Lua.
Does the KOReader.apk have any libs in it?
Or does it presume your device is "Lua-ready"?
The easiest would be to add the libbeluga.so (I presume some pun on "Lua") to the KOReader.apk.
Of, course, if this is the only thing that uses Lua maybe it would be more useful to just patch the code that it doesn't need a foreign language to rotate the screen.
Unless KOReader is all Lua???

I still don't have a clue what libbeluga is.
It appears that it is an optional lib used/not used by libandroid_runtime.so
So it's not like it's not finding a required lib.
