Package: x2goclient
Version: 4.1.2.2

I recently upgraded my workstation to Ubuntu 20.04 and have a small
annoyance with x2go client app: the icon for the remote desktop window
(X2GoAgent) doesn't appear in the dock. It's just a blank square. If I
alt-tab, it shows the mini-window, but also no icon where I'd expect in the
lower right corner.

Setting a custom icon also doesn't work.
