As root with .iftoprc in /root/ on a Dell laptop running Fedora, iftop works for me.
Is your .iftoprc ok?

The iftoprc is included in the tarball. But even if there is rubbish in the file, iftop should not segfault IMHO ;-)
Here is the .iftoprc (which works on other machines):

This is true.
The iftop you're running doesn't appear to have debugging info in it, so I can't tell much from the bt. Can you recompile with debugging info. I think "CFLAGS=-g && make clean && make" should do the trick.
Please just cut and paste the trace into the email - I'll respond quicker that way :-)
thanks,
Paul
