I don't mind the browser being replaced with an individual application
vs a suite of integrated applications for email, browsing and editing. I
miss the missing editing feature the most.
How in the world do you get seamonkey and its corresponding .so files
into the selinux fold? Or better yet, are there guidelines and
assistance given to the Fedora-Extras maintainer that allow their rpms
to set items to the needed SELinux content, in order to work out of the box?
Best cure is avoid DT_TEXTREL shared libraries. Even on the platforms
that (in a limited way) allow them, they are very costly and insecure.
See
http://people.redhat.com/drepper/textrelocs.html
for details. If you fix it up, you don't need any special selinux policy
changes.

This particular library outputs the below. Running with the eu-readelf
-d /usr/lib/seamonkey-1.0.4/libxpcom_core.so shows TEXTREL as blank. I
don't understand anything regarding the output. I do know that SELinux
does not like libxpcom_core.so
I am reading the material that you posted a link to. When (or if) I
grasp the concept, I'll at least follow-up on filing a bug report
against the culpret.
