Dropbox says my environment doesn't support tray icon, by it does

Hi Andsmi​,

I've checked with the team and they said that Dropbox uses DBus to find the app indicator services, so you'll have to make sure that the org.kde.StatusNotifierWatcher service is running. You can do that by running the following command in your terminal:

dbus-send --session \ --type=method_call \ --print-reply \ --dest=org.freedesktop.DBus \ /org/freedesktop/DBus \ org.freedesktop.DBus.ListNames

You should get a list of service names returned, and you should find org.kde.StatusNotifierWatcher in that list.Assuming you see that, you can then query the status of the service using the same DBus message that the Dropbox app uses with the following command:

dbus-send --session \ --type=method_call \ --print-reply \ --dest=org.kde.StatusNotifierWatcher \ /StatusNotifierWatcher \ org.freedesktop.DBus.Properties.Get \ string:org.kde.StatusNotifierWatcher \ string:IsStatusNotifierHostRegistered

If Gnome is properly using the service you should see something like this:

method return time=1748612867.079169 sender=:1.25 -> destination=:1.239 serial=4372 reply_serial=2 variant boolean true

That boolean true is the important part that tells you the service is running and a host is registered.If the appindicator shell extension is properly registering a host and the DBus service is exposed then you should not see that error message.Gnome is currently on version 48, and the appindicator shell extension is currently at version 60, so updating those items may help resolve the issue.
