After importing an address book exported from Netscape 4.61 (which may
have nothing to do with the problem, as I had done nothing before that):
 
I got the same problem with the Netscape on the RH7.0 CDs, then got the
later RPMs from Redhat (4.76).  Still get a SIGBUS/SIGSEGV when doing
the following:
 
From Messenger->New Msg->address; highlight address; then select "To:" and
seg violation.
 
Additionally, the processor is a 1.2GHz AMD Athlon.

Program received signal SIGSEGV, Segmentation fault.
