title: PyCharm debugger doesn't show objects' content: "Unable to get repr for <type 'list>"
body: <p>Debugging with PyCharm (happens on multiple versions) I'm unable to correctly view some lists and dictionaries (other are presented correctly).
  In the view window the object's name is presented with the message:
  <code>{list} Unable to get repr for &lt;type 'list&gt;</code>
  or
  <code>{dict} Unable to get repr for &lt;type 'dict'&gt;</code></p>
  
  <p>An update:
  In one of my attempts, I received the following message from the debugger (presented instead of the value of one of the list variable):</p>
  
  <blockquote>
    <p>Unable to display children:Error resolving variables Traceback (most
    recent call last): File "/Applications/PyCharm
    CE.app/Contents/helpers/pydev/_pydevd_bundle/pydevd_comm.py", line
    1004, in do_it
    _typeName, valDict = pydevd_vars.resolve_compound_variable(self.thread_id, self.frame_id,
    self.scope, self.attributes) TypeError: 'NoneType' object is not
    iterable</p>
  </blockquote>
  
  <p>I'll appreciate any idea as for what may cause this behavior?</p>
  
  <p>Thanks!</p>
