The python bindings in RHEL-5 differ significantly from those of RHEL-6, and those particular leaks are not present in RHEL-5 AFAICT (hence NOTABUG).
The bindings in RHEL-5 might well have some other leaks (the old librpm API has some unfixable leaks in itself), but those would need to be analyzed separately. Since you already have a workaround in place anyway, I dont think its worth the trouble for RHEL-5 at this point.
