pacman seg faults when upgrading module-init-tools with other upgrades (pacman -Syu) and /etc/modprobe.devfs exists in filesystem (i had touch'ed it to make modprobe stop showing the error)

when i tried to upgrade the module-init-tools package alone
(pacman -S module-init-tools)
it failed but it didn't seg fault..
[root@wire conf]# pacman -S module-init-tools

when i upgraded module-init-tools only :
<code>
Targets: module-init-tools-3.0-2

Proceed with upgrade? [Y/n]

checking package integrity... done.
loading package data... done.
checking for file conflicts...
error: the following file conflicts were found:

when i upgraded all the packages :
<code>
[root@wire conf]# pacman -Su
