Denials when installing from updates-testing



This morning I used yum to install the latest packages from the
updates-testing repository for F8.  Some SELinux denials meant that
problems were reported with a lot of these updates e.g.

  Updating  : libxml2                      ##################### [  1/145]
error: %post(libxml2-2.6.32-1.fc8.x86_64) scriptlet failed, exit status 255
  Updating  : gtk2                         ##################### [  2/145]
error: %post(gtk2-2.12.8-2.fc8.x86_64) scriptlet failed, exit status 255
  Updating  : libxslt                      ##################### [  3/145]
error: %post(libxslt-1.1.23-1.fc8.x86_64) scriptlet failed, exit status 255
  Updating  : evolution-data-server        ##################### [  4/145]
error: %post(evolution-data-server-1.12.3-5.fc8.x86_64) scriptlet
failed, exit status 255

and here are excerpts of the sealert messages:

Does this look like a local problem and relabelling is needed?
