Description Julio J. 2014-02-13 02:10:06 UTC 
Application: konsole (2.12)
KDE Platform Version: 4.11.97
Qt Version: 4.8.2
Operating System: Linux 3.2.0-58-generic x86_64
Distribution: Ubuntu 12.04.4 LTS

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

I had 3 instances of the app opened, one of them had a big scrollback, I pressed Ctrl+Shift+F to search on the text and the three instances went away.

First time ever that something like this happened to me, even with larger scrolls.

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

Comment 1 Kurt Hindenburg 2014-02-13 02:41:35 UTC 
Looks like somehow _searchBar no longer exists

void SessionController::searchBarEvent()
{
    QString selectedText = _view->screenWindow()->selectedText(true, true);
    if (!selectedText.isEmpty())
        _searchBar->setSearchText(selectedText);

    if (_searchBar->isVisible()) {          <-- looks like crash here
        _searchBar->focusLineEdit();
    } else {
        searchHistory(true);
        _isSearchBarEnabled = true;
    }
}

KDE4/Konsole4 is no longer maintained. Reopen if you can still reproduce this issue with a current Konsole version.
