Comment 72 for bug 1292290

I confirm this with Ubuntu 14.04.2 with XFCE provided by the xubuntu package: I delete .config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml, log in and set the shortcut; it works. Then if I log out and back in again it doesn't work, despite the shortcut definition being shown by the applet, by xfconf-query and by inspecting the xfce4-keyboard-shortcuts.xml file.

I've tried saving the xfce4-keyboard-shortcuts.xml when the shortcut works, and copying it back in again after the logout/login sequence (when it's stopped working) and it makes no difference; it doesn't look like the problem lies in the shortcuts file itself.

I'd love to contribute to fixing this but I haven't the skill; it's really disruptive.
