konqueror die with Broken pipe

[Low Swee Leong-A16957]

    my configure script is follow:

    ./configure --prefix=/home/sllow/qtopia-free-1.5.0  --enable-qt-embedded --enable-embedded --enable-qtopia --disable-threading --disable-mt --enable-qpe --enable-add-ons=kflashpart,kplaintext,jsdebug --enable-readwrite --enable-ftp  --enable-cgi --enable-sortdir --enable-jshostext --with-qt-dir=/home/sllow/qt-2.3.3 --with-qt-includes=/home/sllow/qt-2.3.3/include --with-qt-libraries=/home/sllow/qt-2.3.3/lib --with-qtopia-dir=/home/sllow/qtopia-free-1.5.0 --with-gui=qpe


    when i run with ./konqueror -qws


    i get the following error:
    Connected to VFB server: 240 x 320 x 16
    debug: KFlashFactory::KFlashFactory
    Launcher::dispatchLoop()...
    QGList::locate: Index -1 out of range
    QGList::locate: Index -1 out of range

    launcher: creating slave for protocol
    Segmentation fault
    launcher: error sending launcherSlavePidCmd: Broken pipe
    konqueror: launcher.cpp:313: bool KIO::Launcher::createSlaveInternal (const char *, cmsghdr *): Assertion `slave' failed.



    does anyone know whats that error means ?
    what is launcher doing ?
    is segmentation fault causing launcher to die or launcher causing segmentation fault ?
    it dies when the creating a internal slave when the protocol is nothing. why is that happening ? why it call that function while starting ?
