Description of problem:

Package xulrunner 1.9.2 (released alongside firefox 3.6.4) no longer provides /usr/lib[64]/mozilla.  This could lead to dependency resolution of another package that does, such as kdelibs.

Version-Release number of selected component (if applicable):

1.9.2 and later, RHEL 5.5 errata RHSA-2010-0501
  http://rhn.redhat.com/errata/RHSA-2010-0501.html  

How reproducible:

Depends on packages installed.  Systems without KDE could resolve to installing KDE to resolve dependency for /usr/lib/mozilla or /usr/lib/mozilla/plugins

Steps to Reproduce:
1.  Install RHEL 5 prior to RHSA-2010-0501 without KDE, but packages with dependency's on /usr/lib/mozilla[/plugins]
2.  Upgrade firefox to version in RHSA-2010-0501
3.
  
Actual results:

Expected results:

KDE packages not installed, only xulrunner (and other, related dependencies)

See Fedora BZ#131667 for decision to provide /usr/lib/mozilla[/plugins]
See RHEL BZ#607781 to reconsider this.
