Links category can be set to blank

A users signaled he was able (by mistake) to edita a link category, setting its name to nothing and saving it. Now the category show as blank in categories list without the checkbox and with any chance to change it in any way.
I tested it personally and it's true, I didn't check if post categories act in the same way.
