I'm afraid this is the first I've heard of a "html>:" flavoured Blosxom. Try dropping the "/+html>:" bit from the end of the URL.
% ls -l /var/crash/ total 3183838 -rw-r--r-- 1 root wheel 3 Nov 2 02:09 bounds -rw-r--r-- 1 root wheel 5 Jun 30 2004 minfree ... -rw------- 1 root wheel 181265401 Nov 2 02:11 netbsd.26.core.gz -rw------- 1 root wheel 2162696 Nov 2 02:11 netbsd.26.gzIn /var/crash, "bounds" contains an increasing counter for the crashdump number (it would be "27" in the above example), and "minfree" contains the minimum amount of free space in kilobytes that should keep free - both files are read by savecore(8) when /etc/rc.conf has "savecore=yes", which is the default.
The actual crashdump consists of two gzipped files - the actual memory dump "netbsd.XX.core.gz" and a copy of the running kernel "netbsd.xx.gz". After uncompressing the files can be used for looking at the system at the point of it's panic:
# gunzip netbsd.26*.gz #Note that the crashdump may contain sensitive data and is such only readable by root!
The crashdump can be read by programs that use libkvm to read through the crashdump's kernel memory, e.g. gdb(1), dmesg(8), ps(1), fstat(8), ipcs(1), netstat(8), nfsstat(8), pmap(1), w(1), pstat(8), vmstat(8) etc., using the -M and -N switches.
Some examples:

Update: Apparently 'target kcore' was renamed to 'target kvm' in gdb6, see this posting.
