Having trouble remote debugging with Django
I'm new to Python but am a long time user of IntelliJ IDEA for Java, so I've been trying to get started using the Python plugin. I am running a Django app in a locally hosted VM, and I'm trying to remote debug it from my MacBook Pro. I have tried both with IDEA and PyCharm and I get the same behavior: my app freezes upon executing the 'setTrace' call and never returns. I have to send it a control-C to kill it.
According to this Stack Overflow answer, it doesn't work to call setTrace from Django until everything is done:
So I added these lines to the bottom of my manage.py file:
pydevd.settrace('220.127.116.11', port=8005, stdoutToServer=True, stderrToServer=True)
print "Finished setting debugger"
I find that I have to hit control-C to get PyCharm to enter the debugger, but when I hit play to restart I find that Django has stopped responding to web requests. If I move the lines of code earlier I don't have to hit control-C, but I still find that Django stops responding once I resume.
Can you offer any help in debugging this problem. Is this something that I've misconfigured, or does it represent a problem with the PyCharm plugin?
P.S. Here's a stack trace I get after killing the process. It seems to be stuck in _locaked_settrace, but I don't know why.

I should have specified my environment:
Mac OS X 10.8.5
IntelliJ IDEA 12.1.6
I have a colleague who told me that she had successfully done this on an earlier version, and I have replicated this. So these steps work with IntelliJ IDEA 12.0.4 which uses a slightly earlier version of the Python plugin (2.10.0). For now I will stay on this earlier version, but I'd like to work out why there is a problem with the later versions.
