/usr/X11R6/bin/mozilla: error while loading shared libraries:
libgtk-1.2.so.0: cannot open shared object file: Input/output error
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
What could the error message mean?
A `shared object' file, as the name itself implies is the object file that is shareb by many programs. You have a bunch of them put up in /usr/lib. It is a DLL (dynamic linked library), which is linked at runtime. Your error suggests that GTK is not installed properly, try reinstalling it. Uninstall can be done with rpm -e <pkg name>. Then again install the GTK rpm, and yes, take care of the dependencies while install/uninstall process.
Also, on a second thought, try replacing libgtk.
