Application: kile (2.1.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Pasting three lines of text copied from kile. Pasted onto a selected line (consists of 4 spaces). Happens consistently but not everytime.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kile (kile), signal: Segmentation fault
