Sentry Crash Report:

Description Antonis Kanouras 2013-11-24 11:51:47 UTC 
Application: kdevelop (4.5.1)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

I had a Django project loaded with mostly Python source files open.

I think the steps that lead to this were:

1. I typed "o" in a Python file
2. The completions window popped up and froze (This happens often, lasting 5-15 seconds usually)
3. I immediately pressed Backspace
4. Kdevelop crashed

This is the first time that this sequence of steps led to a crash.

Please contact me if there's anything more I can do to help debug this.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
