Hrrm, it seems that having the 'root' set to "" was causing the problem.
Chaning root="" to root="/" makes everything work.
Here's the relavant python code:
root=""
print "reading RPMS in " + rpm_dir
hdList = readHeaders(rpm_dir)
list = hdList.keys()
print "found %d unique packages" % len(list)
db = rpm.opendb(1, root)
ts = rpm.TransactionSet(root, db)
When I finally did the 'ts.run' later, everything worked *except* for
removeing a previously installed RPM. Here's a backtrace from GDB:
