Description of problem:

I have had numerous problems with segmentation faults while attempting to
install RPM's. I haven't seen a pattern with what rpm's cause this, some RPM's
install fine, others cause a segmentation fault. Using strace, I found that the
segfault occurs immediately after rpm reads /etc/nsswitch.conf. As I have made
changes to this to get information out of ldap, I figured it was worth a shot to
try and make it stock. Sure enough, after removing 'ldap' from the entries in
/etc/nsswitch.conf, several rpm's I had been unable to install worked fine. 

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. attempt to install rpm

Actual Results:  rpm segmentation fault

Expected Results:  installation of rpm

Additional info:

Here is a diff between my nsswitch.conf (that causes the segfaults) and the
stock version:

[root@hooloovoo archives]# diff /etc/nsswitch.conf /etc/nsswitch.conf~

An example RPM that I had this problem with was:
