Default multipath produces a segmentation fault

CentOS 5.3 with kernel 2.6.37.6 and device-mapper-multipath-0.4.7-42.el5_6.2.

When I run multipath -v9 -d I get:

sdg: not found in pathvec
sdg: mask = 0x1f
Segmentation fault

If I strace the command I see:

stat("/sys/block/sdg/device", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0
write(1, "sdg: not found in pathvec
", 26sdg: not found in pathvec
) = 26
write(1, "sdg: mask = 0x1f
", 17sdg: mask = 0x1f
) = 17
readlink("/sys/block/sdg/device", "../../../6:0:0:16"..., 256) = 17
lstat("/6:0:0:16", 0x7fff04d304c0) = -1 ENOENT (No such file or directory)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

Any ideas what is wrong please ?
