I'm not certain how meaningful this backtrace is.  It is possible that a
very great number of fonts is prompting lwlib to create a widget with
invalid geometry, but that is not consistent with `BadName'.  Would you
mind reproducing this crash after executing:

    (x-synchronize t)

and posting a backtrace produced in such an environment?
