Where are the strings in gc.get_objects?

Hello all. I'm tracking down memory leaks in my app. To do this I wrote a
script to show the numbers of each different type of object. But it doesn't
show strings! Here is the script:
import gc,types
def printDict(d):
keys = d.keys() ; keys.sort()
print '-' * 30
for key in keys:
n = d.get(key)
print '%+6d %s' % (n,key)
d = {} ; d2 = {}
for obj in gc.get_objects():
t = type(obj)
r = repr(t)
n = d.get(r,0)
d[r] = n + 1
if t == types.InstanceType:
t = obj.__class__
r = repr(t)
n = d2.get(r,0)
d2[r] = n + 1
printDict(d)
printDict(d2)
And here is example output. The first part of the listing shows the 'raw'
type of each object, the second part of the listing shows
type(obj.__class__) for instance types.

I get similar results on both Python 2.4 and Python 2.5. I'm running on XP.
Can anyone explain were the strings are? I expect at least twice the number
of strings as there are leoNodes.vnode objects.
