I suspect that you have some X drivers left over from the nVidia
installation.  It's quite possible that your apps are calling one
of these X libraries, which in turn is looking for the nVidia
library, which isn't there anymore.  The trick is to re-install
the Fedora libraries.  I don't remember which ones they are, but
it's easy enough to simply re-install X.  It'll take a little
time, but it works, and you'll know that everything is up to date.
Run the following commands as root and (assuming this is your
problem) you should be okay:

# yum reinstall xorg-x11-\*
# setsebool -P allow_execstack 0

The first re-installs X11, and is the key.  The second is for
systems running SELinux, which includes Fedora.  It closes a
security hole that nVidia opens.

Hope this helps!
