Establishing why an object can't be pickled

I'm receiving an object, t, from an api of type Object. I am unable to pickle it, getting the error:

  File "p.py", line 55, in <module>
    pickle.dump(t, open('data.pkl', 'wb'))
  File "/usr/lib/python2.6/pickle.py", line 1362, in dump
    Pickler(file, protocol).dump(obj)
  File "/usr/lib/python2.6/pickle.py", line 224, in dump
    self.save(obj)
  File "/usr/lib/python2.6/pickle.py", line 313, in save
    (t.__name__, obj))
pickle.PicklingError: Can't pickle 'Object' object: <Object object at 0xb77b11a0>

When I do the following:

for i in dir(t): print(type(i))

I get only string objects:

<type 'str'>
<type 'str'>
<type 'str'>
...
<type 'str'>
<type 'str'>
<type 'str'>

How can I print the contents of my Object object in order to understand why it cant be pickled?

Its also possible that the object contains C pointers to QT objects, in which case it wouldn't make sense for me to pickle the object. But again I would like to see the internal structure of the object in order to establish this.
