I’ve done a little more research using what’s available via F-Droid:
- 5.0.1.24 starts without problems
- 5.1.0.25 starts without problems but has a corrupted icon
- 5.2.0.26 exhibits the problems (but with a good icon).
However all three versions are rather old compared to what’s available on the Minetest website.
I see that the warning W concerns
/storage/emulated/0/Minetest
but the error E is from/storage/emulated/0//Minetest
(or is that just a typo?)
I copied directly from logcat, so the double slash is indeed there. However, it should not make a difference.
