[Bug 201994] New: using krunner in QuickSand Mode and moving with cursor keys crashed

https://bugs.kde.org/show_bug.cgi?id=201994

           Summary: using krunner in QuickSand Mode and moving with cursor
                    keys crashed
           Product: krunner
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: plasma-bugs@xxxxxxx
        ReportedBy: kollix@xxxxxx


Application that crashed: krunner
Version of the application: 0.1
KDE Version: 4.2.98 (KDE 4.2.98 (KDE 4.3 RC3)) "release 150"
Qt Version: 4.5.2
Operating System: Linux 2.6.27.25-0.1-pae i686
Distribution: "openSUSE 11.1 (i586)"

What I was doing when the application crashed:
playing with krunner in QuickSand Mode I typed "bug" and in the right list
which gave some entries I moved with the cursor keys which lead to the crash.

It seems to always crash, when the resulting list here shows:
Wink - [Homepage]
Kdbg ...
KXSLDbg ...
Wink - [Homepage]

I don't know why the first ist the same as the last entry, but moving the
cursor onto the last one produces the crash.
NOTE: In the QuickSand window, I only see 3(!) icons, but the right window with
the list shows "1 of 4"
