           Summary: "Automatic" kded crash caused by double free in
                    kwallet/authinfo
           Product: kdelibs
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: kded
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: rototor at rototor.de

Application: kded4 ($Id$)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
This crash happens always when I use KDE4. Its just a matter of time before
this crash happens in the session.   

This is nothing new to me. I´ve got this problems since KDE 4.4 or somthing
like this. It was frequently annoying in Ubuntu 10.10, even with the KDE 4.6
backports (ppa). But in Natty 11.04 it has now become a killer. Kontact/kmail
renders unusable because the connections to my local IMAP Server (with
selfsigned cert) break all the time and kmail asks my all the time when it
tries to do something on the imap server (i.e. displaying emails). I think this
is connected with the crash as AFAIK the imap KIO stuff is forked off the kded
deamon, isn´t it?

This crash report here is happening while using Gnome. As KDE was not longer
usable i migrated my email/organizer stuff to evolution and now use a gnome
desktop. I only use kwin, konsole and akregator (since Gnome has AFAIK no
usable RSS Reader....; Evolution just does nothing when trying to register my
self signed HTTPS-Trac-RSS Feeds). The crash you can see here has been caused
by opening akregator and waiting for some minutes...

I think this might be caused by the kwallet file i use. I use KDE since
1.0beta3; I think the last time i erased by .kde dir was at KDE 3.2 time. So my
kwallet-file has not been deleted for a long time. And i really dont want to do
delete it.

Im using the properitary NVIDIA driver. I even downgraded to use the open
source nvidia driver (because some properitary nvidia_tls-libs where in the
callstack). But that didnt change anything. 

- Unusual behavior I noticed:
Everything depending on KDED is fucked up... The most annoying thing is: I have
some Servers which have selfsigned certs. Everytime Akregator tries to access
them it asks me if I trust those servers. And I always say "Permanently" -- but
some minutes later I´m asked again. I think this has something to do with the
crashed kded. This is annoying, because after having my laptop run over night I
have about 200 messages dialogs asking me if i want to trust the server..... I
can provide a screenshot of that if you need it :)

Also those message boxes steal the focus from my vmwares, so thats annoying
too.

Plese contact me if you need any future infos. The last time KDE was a great
experience for me was with KDE 3.5 - which is a pitty given that you put such
great effort into KDE.

The crash can be reproduced every time.
