Bug Description

Binary package hint: xfce4-xkb-plugin

Whenever I add the plug-in to the panel, after a few times I switch layouts using the keyboard shortcut it crashes. Each time I have to reconfigure it.

Now it crashed again right after resuming from suspend to RAM, so changing layouts may not be the (only) cause.
The same fields from the apport report:
