Thanks a lot,

Just to make sure I understood it clearly, the Shell will match the
StartupWMClass property of a desktop file and, if it fails, the match
will be on the .desktop file name, is this correct?

If it is, I could match my dumb application (that uses two WM Classes)
by relying on the StartupWMClass for one wm_class and on the file name
for the other wm_class. What if I have an even worse application that
comes up with three different wm_class values (I hope that won't ever
exists)? Can I specify multiple StartupWMClass values in a desktop file?
Does my question make any sense?


Anyway, If the patch within the linked bug makes its way into 3.4.1 it
would be very very sweet, well done GNOME!
