I've had the strangest thing just now. I just noticed all the widgets just vanished. This was after I was listening to music over a bluetooth headset. I couldn't add them back so I rebooted but they still weren't there. I left the phone for 10 minutes and then tried to re-add them to the desktop. As I added the ones I use, they appeared in the same locations as before, but only if I selected to add them.

Has anyone else experienced this?

I am not using devel or testing.
The only updates that came through were for Pidgin Bonjour/Butterfly and I think GConvert.

Everything appears to be back now, so I wonder what caused it ?
