Netscape on Redhat 6.1 for Sparc dumps core ("bus error") when
exiting  the program.  As a result, new bookmarks and other
user settings never make it to their respective files
in .netscape.

No other problems with the program are known to me, and
the error occurs with both the navigator and with the
communicator package.

I have saved the core file and, just in case, make it
available at
