The reason for this behavior is how the PhantomJS driver's Service class is implemented.
There is a __del__ method defined that calls self.stop() method:
def __del__(self):
# subprocess.Popen doesn't send signal on __del__;
# we have to try to stop the launched process.
self.stop()

And, self.stop() is assuming the service instance is still alive trying to access it's attributes:
def stop(self):
"""
Cleans up the process
"""
if self._log:
self._log.close()
self._log = None
#If its dead dont worry
if self.process is None:
return

...

The same exact problem is perfectly described in this thread:
Python attributeError on __del__
What you should do is to silently ignore AttributeError occurring while quitting the driver instance:
try:
driver.quit()
except AttributeError:
pass

The problem was introduced by this revision. Which means that downgrading to 2.40.0 would also help.
