I have confirmed that the RV view looks better now!  Thanks guys!

FYI: I have pushed the updated 0.12.15 rpms out to the repositories
available here:

http://download.opensuse.org/repositories/home://ghaskins://lttng/

    Note: I still only have *suse support since other distros have a
build error I have yet to resolve.  For instance, here is the error on
the RHEL-5 build:

    libtool: install: warning: remember to run `libtool --finish /usr/lib'
    test -z "/usr/include/ltt" || /bin/mkdir -p "/usr/include/ltt"
    /bin/mkdir: cannot create directory `/usr/include/ltt': Permission
denied
    make[2]: *** [install-lttincludeHEADERS] Error 1
    make[2]: Leaving directory
`/usr/src/redhat/BUILD/lttv-0.12.15-16062009/ltt'
    make[1]: *** [install-am] Error 2
    make[1]: Leaving directory
`/usr/src/redhat/BUILD/lttv-0.12.15-16062009/ltt'
    make: *** [install-recursive] Error 1
    error: Bad exit status from /var/tmp/rpm-tmp.10077 (%install)

    Patches for the .spec file welcome!
