Description Gerald Senarclens de Grancy 2013-09-09 10:02:55 UTC
Trying to port pulp-or to be both Python 2 and 3 compatible, I edited their file bootstrap.py.

Reproducible: Always

Steps to Reproduce:
1. ensure python autocompletion works
2. load the attached tc.py file
3. on the second line, type "o" directly after "... import url"
Actual Results:  
kdevelop crashes

Expected Results:  
autocompletion works (once Python3 support is finished)
