           Summary: General KDE crash after unlocking screen and
                    re-enabling wifi
           Product: kdelibs
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: kded
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: caterpillar86 at gmail.com


Application: kded4 ($Id$)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.35.12-88.fc14.i686 i686
Distribution: "Fedora release 14 (Laughlin)"

-- Information about the crash:
I was in a library and using the computer with wifi connection. Once I closed
the monitor lift to lock the screen and I moved away...
Once I returned in the library, I opened the monitor, I entered the password to
unlock the monitor and then entered the password of KDE Wallet to be able to
connect again to the wifi. After that KDE freezed for 3-5 seconds and I got
again a "enter password to unlock screen" window.

-- Backtrace:
Application: Demone KDE (kded4), signal: Segmentation fault
