21957	[Patch] Duplicate dock icon in GNOME	CjMalone	team	"In GNOME (and presumably other desktops) when JOSM is favourited and running you get 2 different icons. One is for ""org.openstreetmap.josm.desktop"" and the other ""org-openstreetmap-josm-gui-MainApplication"", you can link the 2 with StartupWMClass.

ticket:18013 seems to have spotted this, but r15283 didn't quite fix it.
