Segfault in librpm

[Erwan Velu]

I would need some help as when using yum on my system to setup a chroot, I do have the following backtrace  : http://pastebin.com/zrFmApVM

I'm using RPM version 4.11.1/

I don't understand why fp is null and don't really understand what it means.

To generate this bug, I'm doing
" yum --installroot /var/lib/install/centos-F.1.0.0/base/ install -y --nogpgcheck basesystem "

if some could help, that would be lovely,

Cheers,
Erwan
