strange bug in keybindings screen

[truculentt]

It doesn't produce a bug report, and I can seem to force one either, so I took a screen shot.

No idea what this is.

did some testing. installed a fresh interface, then realui, followed by additional addons 1 by 1.

only happens with realui installed and enabled.
