Arch Linux

Description:
When executing 'guake -e command' I get :
TypeError: Vte.Terminal.feed_child() takes exactly 2 arguments (3 given)

Seems to be exact same error reported by the package maintainer to guake:
https://github.com/Guake/guake/issues/1243

Additional info:
package guake 3.2.0-1
guake -V = Guake Terminal 3.2.0

guake -e xonsh gives:

During handling of the above exception, another exception occurred:
