-- Information about the crash:
- What I was doing when the application crashed:
Searching a word in huge number of lines (few milions):
1. pressed Ctrl+Shift+F -> live search opened
2. entering each letter caused 10 second hang
3. after entering 6 letters and pressing "Next" (to find next occurence)
application crashed

- Custom settings of the application:
scroll entries: unlimited

-- Backtrace:
Application: Konsole (kdeinit4), signal: Segmentation fault
