module weight must be a number (found "") [#985106]

Trying to install one of my module, but I've got following validation errors.

    * The views_slideshow module weight must be a number (found "").
    * The views_slideshow_singleframe module weight must be a number (found "").
    * The views_slideshow_thumbnailhover module weight must be a number (found "").

I can't enable any of the modules.
Why?

Now it works, I didn't change any weight of the module and I don't know how it's possible that it changed by it-self.
Maybe if it's empty, we should assume that's zero?
