Updated Launcher doesn't start (Linux)

Yesterday, I updated my minecraft launcher on my Linux - Manjaro (Arch-based Linux distro) and then it just stopped working.

It crashes always, when I want to start it.

I put here thebootstrap_log.txt, it's the only file that got rewritten.

PS: Sorry for my bad english.

And the version, that shows to me is actually: minecraft-launcher 915-1
