Most programs don't install erro handlers so they print something and then die.

As I said, it can hide a real error.  If a font is invalid it is probably some
user error, i.e. he specified a non-existant font.  But if for example a
window or GC is invalid it is much more likely to be a serious bug in Emacs
internal data structures, and continuing after such an error could lead to all
sorts of nastiness.
