Description PyrosBrother 2008-11-09 15:06:24 UTC 
Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

Since my last update of kubuntu 8.10 KDE Crash at launch time. When i close the crash handler window all things seems to run correctly.

here is the crash handler dump. I have make the dbg packages on to get the maximum of details. If needed I could make more test as you want. I keep my Dell laptop as this to get it possible.

Comment 2 Dario Andres 2009-01-24 16:06:35 UTC 
@Peter (comment ) your report is a completely different one (already reported)
Comment 3 Dan Linder 2009-02-15 00:49:37 UTC 
I've been running into this for a while too.  I'm running Ubuntu 8.10 on an AMD x86_64.  I have two video cards and three displays: an NVidia GF2MX with a single CRT, and an NVidia GF8600 with two LCD panels off of the DVI ports.  I have Xinerama enabled to make the three into one display.

Here are the details from the KDE Crash Handler:

Comment 4 arena.g 2009-04-03 01:21:02 UTC 
I am having the same 'Fatal error' Signal 11 (SIGSEGV).The problem started,also,  after an update.
My PC is an HP with amd64 processor
Ubuntu 9.04 release.
Kernel Linux 2.6.28-11-generic.
Yours,
Gaetano Arena
Comment 5 Christoph Feck 2009-05-09 18:37:19 UTC 
Dan, backtrace in comment #3 is bug 192129.
Comment 6 Christoph Feck 2009-05-09 19:04:31 UTC 
PyrosBrother, the backtrace from the original bug references file names that are no longer in trunk. Could you re-test revision r965732, either current trunk or from 4.2 branch (or wait for KDE 4.2.4 / KDE 4.3.0) to see if the bug is fixed during the module rewrite?
Comment 7 PyrosBrother 2009-05-11 10:23:13 UTC 
hello Christoph,

First of all, thank you for your attention to this point. I will upgrade my Kubuntu and tell you if this point could be closed or not.

Best regards
Stéphane
Comment 8 Christoph Feck 2009-08-08 13:24:03 UTC 
PyrosBrother, any news? The crash should be fixed in KDE 4.2.4 and KDE 4.3.0.
Comment 9 PyrosBrother 2009-08-09 21:36:33 UTC 
Hello Christoph,

thank you for taking care to this point.
Yes I think you could close it now because it seem that it doesn't occur 
anymore.
Sometimes, plasma or other kde components crash but not in the same way 
and with the same result as this point mention to.
So I think that's not the same problem.

Kindest regards.
Stéphane

Comment 10 Christoph Feck 2009-08-09 22:28:37 UTC 
I hope you report the other crashes you get and still enjoy KDE :)

Thanks for the feedback, closing as fixed.
