New crash information added by DrKonqi

kded4 ($Id$) on KDE Platform 4.10.00 "release 546" using Qt 4.8.4

- Unusual behavior I noticed:
Same effect, on every login. I've created a new testuser from scratch -  same segfault after login.

System booted with "nomodeset", same thing happens...

This backtrace is really nonsense...
It crashes because of a null pointer but that pointer was just created so I don't see why it's null, do you have this bahavior at every login?
if you kill kded4 and start it from konsole does it crash too?
Thanks

Yes, this crash happens every time, i logging into my account. I've created a new test-account, with the same effect happening on every boot! The crash happens ca. 30secs to 2mins after KDE4 is fully up. Autostart of jbidwatcher fails, since this failure is present. Maybe, this triggers the bug?

> if you kill kded4 and start it from konsole does it crash too? 

Yes, this happens on every login. I've witched runmode on tty1 from 5 to 3 and back with no change. Same thing if i apply <ctrl>+<alt>+2*<backspace>.

Another thing, happening rarely from time to time:
Everything works fine, when changing from one applicatin to another fails partially. Mouseclicks are focussed to the last App, clicks outside the old window are withot effect. Keyboard works without quirks, i can use all shortcuts within the "new" App. But i can't switch to another app, using <alt>+<Tab>. The only way out of this is mess, is killing kde4 and login again.

can you pkill kded4 and launch it from konsole and wait to see if the same happens?
is it a new F18 install?

> can you pkill kded4 and launch it from konsole and wait to see if the same happens?
Yes, i've done so and the following happens:

After this, all icons on desktop, except the trashcan, dissapeard! The USB-Notifier pops repeatedly up with "the following device cannot mounted: win-partition>" (translated from german)

No, it's a relative fresh openSUSE 12.2. I've updated KDE from 4.8.5 to 4.10 to fix the problems around KDE4. It became unstable last december. At this time, my machine runs openSUSE 11.4. The problems started after one of the regular online-updates. In january, i Installed openSUSE (no upgrade, fresh install).

I've also been having lots of problems with segfaults after upgrading to 4.10
Invariably, they happen when the network is refreshing or right after unlocking the screen.
My tracebacks (konsole crashing) look like this:

hmm looking at you xsession erros file actually showed that your packagekit installation might not be working well, does apper opens and work?
and your last comment is due which application? the tracebacke doesn't seem to be from apper.

Ok, I think I might have fixed the issue (tho if doesn't explain the this=0x0 on the backtrace it might fix the issue:
http://gitorious.org/packagekit/packagekit-qt/commit/da41de0e4a98eed232eb05a14e903666dbb21838

I'll ask fedora ppl to push the patch

ask and ye shall receive,
http://admin.fedoraproject.org/updates/PackageKit-Qt-0.8.7-3.fc18

Yesterday i've updated KDE to version 4.10.1 "release 552". It seems the bug is resolved, no segfault, no lost focus anymore! (Distribution:  openSUSE 12.2 (x86_64))

TIA, peter Huyoff

This doesn't make sense, first because I thought the bug was with a Fedora user
so the update is only in fedora repos and not in openSUSE ones...
Your update probably fixed your PackageKit installation which was actually what
was triggering the bug but doesn't explain much the crash... either way
the code is a bit better now...
