           Summary: Konsole crashed when searching for text while running
                    command
    Classification: Unclassified
           Product: konsole
           Version: 2.13
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi

Application: konsole (2.13)
KDE Platform Version: 4.13.0 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.13.6 x86_64

-- Information about the crash:
- What I was doing when the application crashed:
Konsole suddenly crashed when I tried to search for text through the output
while shell was busy with processing another command. IIRC, I pushed "Back"
button right before it crashed.

-- Backtrace:
