           Summary: In plasma-windowed (Dictionary), entering long string
                    with various whitespace causes segfault
           Product: kde
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: rj.amdphreak at gmail.com

Application: plasma-windowed (0.1)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.1-1.2-default i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
I was looking up a definition. I copied a huge string from Knotes accidentally
instead and pasted it as the word to define. The string I believe was composed
of unix newlines and ASCII chars.
It was 359 words long, 2131 characters long, and 1777 characters long w/o
spaces, according to LibreOffice

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Widgets shell (plasma-windowed), signal: Segmentation fault
