Toolbox upgrade to 2 (nothing displayed / empty window)

Hello,

I am on archlinux and until the the last upgrade of the toolbox application everything worked fine.

The window juste went empty / blank:

I can't see anything.

The toolbox.log only says:

==========================================

Thank you very much in advance for any help.
