           Summary: Crash of kded/KPasswdServer
           Product: kde
           Version: 4.5
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: torpe at laposte.net


Version:           4.5 (using KDE 4.5.1) 
OS:                Linux

At some point during a kde session, a dialog box tells me kde daemon has
crashed. After that, all my authentificated rss feed from akregator ask me for
the user/pwd, although this is normally done transparently. Opening
.xsession-errors seems to tell me kded/kpasswdserver has crashed. While kded is
automatically rebooted, KIO services do not have access to kpasswdserver
anymore, until I reboot or until I put the PC to sleep and then resume.
See below for the complete trace of .xsession-errors. Feel free to ask me more
details.

Reproducible: Didn't try
