Affected QGIS version: 2.14.10
Redmine category:python_plugins

In Windows 7 x64 SP1 using Python 2.7 x64, I installed QGIS 2.14.10 from the standalone x64 installer. I was able to run this script successfully in @2.14.9@, but noticed that since I installed @2.14.10@ the script causes a crash in Python.exe

Script source: http://gis.stackexchange.com/a/223248/36886

from qgis.core import *
from PyQt4.QtCore import QFileInfo
from PyQt4.QtGui import QApplication

QgsApplication.setPrefixPath(r"C:\\Program Files\\QGIS Essen\\apps\\qgis-ltr", True)
qgs = QApplication([], False)
QgsApplication.initQgis()
1. Get the project instance
project = QgsProject.instance()
1. Open the project
project.read(QFileInfo('C:/path/to/project/project.qgs'))
print project.fileName()
1. Get the layers in the project
layers = QgsMapLayerRegistry.instance().mapLayers()

print layers
QgsApplication.exitQgis()

I've tried with two different project files, both of which open correctly in QGIS

Check your path to QGIS:
C:\Program Files\QGIS Essen\apps\qgis-ltr
Does that exist? Or changed to QGIS 2.14?

• priority_id was changed from Severe/Regression to Low
• status_id was changed from Open to Feedback
• category_id was changed from Project Loading/Saving to Python plugins

Yup, still exists. I manually changed it from 2.14 during install so that the install path didn't flip flop between LTR releases.

Upgrading to @2.14.11@ solved this problem.
