Fallback icon is shown after wake up

[xcxjzjjcpr]

I'm using caffeine-ng on Debian with xfce4, which is using the libayatana-appindicator for the tray icon.

After app start one tray icon is shown, which is correct. After waking up the system from sleep there are two tray icons shown. The second tray icon is the fallback icon (GtkStatusIcon). Expected behavior would be to not show the fallback tray icon.
