system-config-printer-gnome has no program class

[David D Lowe]

Binary package hint: system-config-printer-gnome

When adding a printer using the utility provided by default with Ubuntu 9.04, a program class is not correctly set, making GNOME Do call it System-config-printer.py in Docky. It should have been set to "Program Configuration" or similar. Other programs, such as other docks and Compiz Fusion use the program class to select windows.
Fixing the problem is as simple as adding this line of code in the appropriate place:
gtk.gdk.set_program_class(_("Printer configuration"))

$ apt-cache policy system-config-printer-gnome
