When running a python script or executing lines in the python console, if I attempt to import the site module (done by executing the line "import site") the following error message is displayed by the interpreter:
Traceback (most recent call last):

File "<blender_console>", line 1, in <module>

  for m in set(sys.modules.values()):

TypeError: unhashable type: 'list'

It seems that some of the values contained in the dict_values construct returned by sys.modules.values() cannot be added to a set. When comparing the types of objects contained in the dict_values construct between Blender 2.60 and 2.61 there were two new types in the 2.61 version:
<class 'bpy.app.handlers'>
<class 'bpy.app'>

It is my hypothesis that when either of the two objects in the dict_values list that are of these types are being added to the set, the exception is thrown. As a temporary work around, I explicitly make the set by iterating through the list returned by sys.modules.values(), adding each element to a temporary set one at a time. I surround the addition of each element with a try/except block to prevent erroneous objects from being added. A sample is below:
BEFORE:
for m in set(sys.modules.values()):

      if hasattr(m, '__loader__'):
          continue   # don't mess with a PEP 302-supplied __file__
      try:
          m.__file__ = os.path.abspath(m.__file__)
      except (AttributeError, OSError):
          pass
      try:
          m.__cached__ = os.path.abspath(m.__cached__)
      except (AttributeError, OSError):
          pass

AFTER:

  tmpSet = set()
  for foo in sys.modules.values():
      try:
          tmpSet.add(foo)
      except:
          pass
  for m in tmpSet:
      if hasattr(m, '__loader__'):
          continue   # don't mess with a PEP 302-supplied __file__
      try:
          m.__file__ = os.path.abspath(m.__file__)
      except (AttributeError, OSError):
          pass
      try:
          m.__cached__ = os.path.abspath(m.__cached__)
      except (AttributeError, OSError):
          pass%%%
