I'm using Xubuntu 14.04, 64 bit
The output of xfce4-about is
xfce4-about-Message: No vendor information found in
"/usr/share/xfce4/vendorinfo
However I believe I'm using 4.12 but…
Anyway, Everything was working fine, until I had an issue, and had to do sudo apt-get install xubuntu-desktop
Just to be sure that I'm using the latest version that comes with 14.04, and not the official version that comes with 13.10, I upgraded it
$ sudo add-apt-repository ppa:xubuntu-dev/xfce-4.10
$ sudo add-apt-repository ppa:xubuntu-dev/xfce-4.12
$ sudo apt-get update
$ sudo apt-get dist-upgrade
All is fine till today, the top panel is a mess, too many indicators
I can't remove the bluetooth indicator on the left. I can't move any indicator, if I remove any indicator from the panel, the whole panel will be gone.
I tried resetting xfce but does not seem to fix it.
The output of xfce4-panel is

The xubuntu-dev/xfce-4.12 doesn't seem to contain any packages for Ubuntu 14.04 yet (see https://launchpad.net/~xubuntu-dev/+archive/xfce-4.12), so I'm unsure whether you managed to actually upgrade xfce to the latest version? What does xfce4-about return after the dist-upgrade? If not, maybe using the 4.12 package that are meant for older Ubuntu distro's doesn't work as intended?
