What we should do is make the errors prettier.  We should probably use
CGI::Carp qw(fatalsToBrowser); - is that OK by everyone and do we need
this only in C4::Output or in all cgi-bin scripts?

I don't think exceptions are the way to go.  Read the top of perl's
exceptions library:
[...]
# This library is no longer being maintained, and is included for backward
# compatibility with Perl 4 programs which may require it.
#
# In particular, this should not be used as an example of modern Perl
# programming techniques.
[...]

Also, we're never going to catch all errors.  Sysadmins and users
sometimes do surprising things, like transposing fields in the
configuration, or installing new firewalls.
