This is not relevant to the issue at hand.  The assertion violation
you've hit means that the base face of the mode line (known as
'mode-line') is somehow invalid.  Any additional faces you add to the
strings displayed on the mode line are irrelevant.

Do you have any face remappings for the mode-line face itself?  If so,
please show them, and please explain when and how are these remappings
changed.
