Sorry for the detail, i am new to this things.. Just to be clear:

Downloaded source for grub-common
patch from bug=474931#45 applied to disk/lvm.c		"patch lvm.c lvm.diff"
build grub2_1.96+20080429-1_amd64.deb		"dpkg-buildpackage -uc -b " 
said package installed		"dpkg -i grub-common_1.96+20080429-1_amd64.deb"
run grub-probe -t device sda -------> same segfault.

Questions:
Version of grub-probe didn't change, it's still 1.96, Is it correct?
"grub-probe -v -t device sda" produces a long list:

Volación de segmento
<quote/>

Obviously "Violacion de segmento" is a segfault  :-)
is it correct to probe sda5 and sda6 "52 times"?
does this help in any way?

How do I know the patch is in effect?

Thanks for being patient!!!!
