If I have a file that imports "viewsets" from django-rest-frameworks project, kdevelop crashes while trying to type new method, i.e. "def a..", in any class that extends classes from "viewsets" file. See reproduction steps below for details.

kdevelop version 4.7.0
kdev-python version 1.7.0; also tried compiling git master
python version 2.7.6



Reproducible: Always

Steps to Reproduce:
1. cd /tmp/
2. virtualenv dead
3. source /tmp/dead/bin/activate
4. mkdir /tmp/dead-code
5. cd /tmp/dead-code
6. pip install Django==1.7.1 djangorestframework==3.0.0
7. PYTHONPATH=/tmp/dead/lib/python2.7/site-packages kdevelop -n dead
8. import /tmp/dead-code directory as a project into kdevelop
9. create new file "dead.py" with the following contents:

from rest_framework import viewsets


class MyViewSet(viewsets.ModelViewSet):

10.  Wait until everything gets parsed and "viewsets.ModelViewSet" in class definition becomes green.
11.  Start new line after class definition and start typing "def a". Once you type "a", kdevelop will crash. I.e. dead.py would be looking as follows:

from rest_framework import viewsets


class MyViewSet(viewsets.ModelViewSet):
    def a


=============

If you relaunch kdevelop and tell him to recover the file, it will crash again.


Here is the console log with debug enabled after I've started to type "def a":
