            Bug ID: 304837
          Severity: crash
           Version: 2.9
          Priority: NOR
          Assignee: konsole-devel at kde.org
           Summary: konsole crash when editing search text
    Classification: Unclassified
                OS: Linux
          Reporter: wolfgang at rohdewald.de
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: konsole

Application: konsole (2.9)
KDE Platform Version: 4.8.90 (4.8.90)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

entering text in the search widget

and because this bugreporter needs a minimum amount of text...

The crash does not seem to be reproducible.

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