I would try two things. First I would see if there are differences in
the rpms that are installed in both machines. You can do a "rpm -q -a
>somefile" in one machine, do the same on the other ("rpm -q -a
>somefile2") and then compare the two files as in "diff -uNr somefile
somefile2". Just to see if there is something obviously missing in the
computer that is not behaving. 

I would also suspect something you installed manually (fluxbox?)
overwrote a file or library in the qt3 installation. You could check the
integrity of the installed files by doing "rpm -V somepackage" and
replacing somepackage with the name of the package to check. You can get
a list of the qt 3 packages by saying "rpm -q -a | grep qt | grep 3.0"

I agree. Let's see what happens if you try the aforementioned tests...
