Symlinks make addon crashes ?

Hi guys,

I made an addon that includes 'py-sonic' as a git submodule.
The advantage of this is that I can easily update the submodule from the original Github repo.

The library I want to include in my addon is in a subdirectory of that submodule, py-sonic/libsonic
I think python won't let me load a path with a dash in it, and anyway, the py-sonic directory does not have an __init__.py file in it, so unless I make changes in the py-sonic files, I'm not able to load the library.
And I don't want to make changes since I loose al the benefits of the submodule thing

Anyway, there is a simple solution for that : symlinks.
I made a symlink libsonic in /lib/ that links to py-sonic/libsonic.

So I can load the library in python with

import libsonic

and keep the original submodule structure.

It work great on KODI under Mac OS X; but when I try it in LibreELEC, it crashes, saying that libsonic cannot be found.
If I replace the libsonic symlink with the libsonic directory, it works fine.

Any ideas about that bug ?

plugin.audio.subsonic with symlink (crashes)
plugin.audio.subsonic without symlink (works)

Thanks !
