It ran for a while, then stopped without any error messages. But
Fontmatrix still gives the same error message.

The sbin command returned nothing, other than a dozen "no such address
or device" messages. But the lib64 command (in addition to a couple
dozen similar error messages), gave the following:

/usr/lib64/libcucul.so.0.99.17
/usr/lib64/libkdeinit4_plasma-desktop.so
/usr/lib64/libkdeinit4_ksmserver.so

/usr/lib64/libkworkspace.so.4
/usr/lib64/libkdeinit4_plasma-windowed.so
/usr/lib64/libGLEW.so.1.5.5

The first thing I noticed was cinepaint. I tried launching it and
discovered that it won't launch either. However, the error message is
somewhat different:

cinepaint
Locale found in /usr/share/locale
No protocol specified
(cinepaint:6193): Gtk-WARNING **: cannot open display: :0.0

I reinstalled it with yum, but it continues to give the same error
message.

The second thing I noticed is 

/usr/lib64/libkdeinit4_ksysguard.so

Recall that ksysguard was my other app that won't launch and gives the
same error message as Fontmatrix.

I suppose the next thing to do is look through the list of dependencies
for Fontmatrix and cross-reference to the above list.
