This is how I reproduced the bug on a new panel. Note that compositing is disabled, but the Enter and Leave bars for Opacity in the Appearance menu are at 100

1. Add a new Panel, Panel 2
2. In Panel Preferences -> Appearance -> Configure, enable Compositing in the Window Tweaks menu that opens up
NOTE: The Panel Preferences window closes, the debug log says that segfault occurred!
Reopen Panel Preferences
3. Back in Panel Preferences ->Appearance, make Enter and Leave bars to 0
4. Now disable Compositing in Window Tweaks
5. Now add items to Panel 2 - say Power Manager and Notifications Area
6. Close the Panel Pref. menu, and kill xfce4-panel
7. Restart xfce4-panel, and for me, Panel 2 is blank

To make the plugins on Panel 2 reappear,
1. Open Panel Preferences, go to Panel 2
2. In Panel Preferences -> Appearance -> Configure, enable Compositing in the Window Tweaks menu that opens up
3. Make Enter and Leave bars to 100
4. Disable Compositing
5. Plugins on Panel 2 should appear even after killing and restarting xfce4-panel

I have attached the exported panel config also
