To enable automatic debuginfo downloading user needs to tweak the file /etc/libreport/events.d/ccpp_event.conf. It should contain following lines:

EVENT=analyze_LocalGDB analyzer=CCpp
        abrt-action-analyze-core --core=coredump -o build_ids &&
        # In RHEL we don't want to install anything by default
        # and also this would fail, as the debuginfo repositories.
        # are not available without root password rhbz#759443
        # /usr/libexec/abrt-action-install-debuginfo-to-abrt-cache --size_mb=4096 &&
        abrt-action-generate-backtrace &&
        abrt-action-analyze-backtrace

all what's neede is to uncomment (remove leading '#') the line:

# /usr/libexec/abrt-action-install-debuginfo-to-abrt-cache --size_mb=4096 &&

so the final line is like this:

/usr/libexec/abrt-action-install-debuginfo-to-abrt-cache --size_mb=4096 &&

NOTE: please note, that the automatic debuginfo install won't work for non-root when the debuginfo packages are served from RHN repositories - more info: rhbz#759443

To enable bugzilla plugin the following steps have to be done:

1. install libreport-plugin-bugzilla
$ yum install libreport-plugin-bugzilla

2. edit file /etc/libreport/events.d/bugzilla_event.conf and add line:
EVENT=report_Bugzilla reporter-bugzilla -b

- this will enable the bugzilla plugin for ALL types of problem, if user wants to enable it only for a specific type of a problem, the line added to bugzilla_event.conf should look like this:

C/C++ crashes:

EVENT=report_Bugzilla analyzer=CCpp reporter-bugzilla -b

Python crashes:

EVENT=report_Bugzilla analyzer=Python reporter-bugzilla -b

Kerneloops crashes:

EVENT=report_Bugzilla analyzer=Kerneloops reporter-bugzilla -b
