Bug 243137

Application: konqueror (4.4.90 (KDE 4.4.90 (KDE 4.5 RC1)))
KDE Platform Version: 4.4.90 (KDE 4.4.90 (KDE 4.5 RC1))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

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

I executed this little script:
-------------------------
#!/bin/bash
KONQUEROR=$(qdbus | grep -m1 konqueror)
KONQUEROR=${KONQUEROR## }
if [ -z "${KONQUEROR}" ]
then
        echo "No running Konqueror instance found. Please start Konqueror."
        exit 1
fi
dbus-send --session --dest=${KONQUEROR} /KIO/Scheduler org.kde.KIO.Scheduler.reparseSlaveConfiguration
-------------------------

- Unusual behavior I noticed:
Konqueror (together with a lot of other applications) just crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
