menu issue of the readthedocs theme

[xiaopeng163]

when I configured the readthedocs theme, the menu in the left side can not use.

I clicked them, but no response.

the same code if I remove the theme, all works will.

I see the same thing, menu generation for that theme is not working, works on all other themes.

Seems to be the offending line. For some reason nav_item.url is either empty, or simply a '.' dot
