Short description of error

When autocompleting bpy.app.something I get this error:

Traceback (most recent call last):

TypeError: unorderable types: tuple() < str()

Exact steps for others to reproduce the error

Start Blender
Press Shift+F4 to open script window
Type bpy.app.b and then the "Autocomplete" button/hotkey TWICE (first time it's ok)
See the error

Some info about this bug.

It is because version attribute value exists in object attributes names (along with version attribute name)

>>> [item for item in bpy.app.__dir__() if not isinstance(item, str)]

[(2, 78, 0)]

and dir sorts attributes names alphabetically.
This happens only after autocomplete usage (I also tried with bpy.app.b).

Same code for 2.77

>>> [item for item in bpy.app.__dir__() if not isinstance(item, str)]

[]

Bisection result:

    PyAPI: fix memory leaks in dictionary assignment

    Thanks to Kévin Dietrich for spotting driver leak,
    checked other uses of PyDict_SetItem and found more.

Reproducible test:

def test_T49342():
    bpy.app.binary_path_python
    dir(bpy.app)

access to this attribute causes the error. Other attributes are ok

@Stranger6667 Thanks for investigation… blender/blender@f5e020a7a6

However, I cannot confirm this behavior here with own build, neither from master nor 2.78 branch, neither in debug build or release build :|

This may be a python version thing… @Sergey if I am correct, official builds use python 3.5.1 right? While here am using system 3.5.2 one…
