Description of problem:
I have a C utility that uses RPM(version 4.6.0) to install and erase packages. When I run my utility using VALGRIND, I am seeing a bunch of memory leaks in RPM library.



Version-Release number of selected component (if applicable):
RPM Version 4.6.0

How reproducible:
100%

Steps to Reproduce:
1. Any C utility that uses RPM version 4.6.0 to install and erase packages.
2. Need to use valgrind, with memcheck and leak options turned ON.
Note:: For the case below, I was installing 1 package and erasing 1 package.
  
Actual results:

Memory Leaks reported by valgrind.
Note::You will also see the api names of the C utility that call RPM apis.
