This is indicative of a bug in multipathd.  It might or might not be
serious, but I guess Christophe Varoqui would be interested in seeing a
backtrace of the segfault in any case...

Try running multipathd (make sure it's not stripped of debugging
symbols) with core dumps enabled ("ulimit -c unlimited"), and get a
backtrace ("gdb /sbin/multipathd core" - then run "bt full").
