What about adding some environment variable check, PYSIDE_INIT_OPENSSL:
# On Windows add the PySide\openssl folder (if it exists) to the
# PATH so the SSL DLLs can be found when Qt tries to dynamically
# load them. Tell Qt to load them and then reset the PATH.
if sys.platform == 'win32':
initOpenSsl = os.environ['PYSIDE_INIT_OPENSSL']
opensslDir = os.path.join(pysideDir, 'openssl')
if initOpenSsl and os.path.exists(opensslDir):
path = os.environ['PATH']
try:
os.environ['PATH'] = opensslDir + os.pathsep + path
try:
from . import QtNetwork
except ImportError:
pass
else:
QtNetwork.QSslSocket.supportsSsl()
finally:
os.environ['PATH'] = path
