That doesn't make much sense (read: is probably plain wrong), if $file
is a HTML file.

As you first write correctly, it doesn't crash, it panics. That is by
design. A lot of people doesn't like this design decision, but only
because you don't like it too doesn't mean it isn't
deliberate. Although I've learned in several discussions about this
topic, that most don't want to hear my arguments.

In my book, it is far away from being that simple.

To make the long story (that anyway almost nobody want to hear) short:
you've an encoding problem. That means, you've a very elementary,
real, hard, systematic problem.

The panic is there, to put your noise with most possible severity into
that.

The tdom core, if used proper, seems to be rock-solid, for all what I
can tell. No, what you see isn't due to a modificacion, that is the
way it is since years and years.
