           Summary: crash in kpasswd
           Product: kdelibs
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: kded
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: jtamate at gmail.com


Application: kded4 ($Id$)
KDE Platform Version: 4.7.4 (4.7.4) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-2-desktop x86_64
Distribution: "openSUSE 12.2 Milestone 0 (x86_64)"

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

Introducing the router passwd in konqueror.

I can tell why it happened....
In kpasswdserver.cpp at line 676 there is:
    delete request;
At line 718 there is:
    m_authPrompted.removeAll(request->key);
(yes, request has been deleted previously).

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
