Version-Release number of selected component (if applicable):
[bill@pikachu bill]$ rpm -qa | egrep mozilla
mozilla-mail-0.9.8-2
mozilla-psm-0.9.8-2
mozilla-0.9.8-2
mozilla-js-debugger-0.9.8-2
kdebindings-kmozilla-3.0.0-0.cvs20020218.1
mozilla-devel-0.9.8-2
mozilla-chat-0.9.8-2
mozilla-dom-inspector-0.9.8-2

How Reproducible:
Try to run mozilla as non-root.

Additional information:
It works if I run mozilla as root.  This doesn't happen if
/usr/lib/mozilla/component.reg is made writable by the user.  The trace when run
as root looks like this:
