fresh install segfault

[LeSpatiocorne]

I've got a segfault on fresh install and can't even launch properly the server.
At first, I thought that was because of the host install I was using, so I tried a local install but got the exact same result !

Find and delete the libparty.so file from CoreKeeperServer_Data/Plugins.

Saw it on a reddit thread somewhere and it works.
