Hello Graeme Vetterlein, I have reassigned the bug to package libwnck-3-0.
Just later I saw that there was already a release:
Changes:
libwnck3 (43.0-3) unstable; urgency=medium
.
* Backport four upstream commits to fix Xfce X2Go sessions.
(Closes: #1021685, #1025174)
Is your issue fixed with this version?
Kind regards,
Bernhard
