           Summary: Bad behavior on closing (Computer vs. Computer)
                    [QProcess::readChannel,
                    QProcess::readAllStandardOutput,
                    Kigo::Game::waitResponse]
           Product: kde
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: johannesobermayr at gmx.de


Application: kigo (v0.5.5)
KDE Version: 4.3.72 (KDE 4.3.72 (KDE 4.4 >= 20091015)) "release 2" (Compiled
from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.31.3-1-pae i686
Distribution: "openSUSE 11.2 RC 1 (i586)"

What I was doing when the application crashed:
If you "do" a Computer vs. Computer game there is a very bad behavior on end of
game:

Moves docker:
flood of messages

"Finish Game" in Main-Toolbar blinks all time...

"%1 has won this game with a score of %2." appears/disappears also all time.

After closing this crash occurs...

I know it is stupid to do a "Computer vs. Computer" game. But as a free time
translator you do not have unlimited time...
