Comment 5 for bug 1807602

Thanks for the hint. I installed scilab from scratch like this:

sudo apt install -t bionic-proposed scilab

To make sure that all packages comes from -proposed.

Now when it is called from its graphical launcher, it flashes for a second then closes. It runs when it is called from the terminal.
