It of course should not crash, it would be useful to have a backtrace from the
core file that was generated.

It looks like PKI cannot be contacted. I would recommend checking
/var/log/httpd/error_log, it may have more details. I would also recommend
checking "ipa cert-show 1", it will probably fail with the same bug.

Next steps may include checking that dogtag service really runs, there is no
SELinux AVC. If neither of this helps, you can check PKI logs /var/log/pki...
to see what went wrong.

Some pointers to logs are for example here:

This should not cause this error, it is more about performance tuning, AFAIK.
