Bug 158662

Plasma error when logging in - black screen opens debugger & firefox & klorenz.kss opens?

Hi John, are you sure, that you updated whole of KDE4? So, kdelibs, kdebase and probably also extragear? Also, does it work if you do
mv ~/.kde4/share/config/plasma-appletsrc ~/.kde4/share/config/plasma-appletsrc-OLD
and then startup again?

As probably pointed out at comment #1 it may also interesting to have a backtrace of the crash. You are able to catch one by;
* Be sure you have the debug-packages installed. So, e.g. kdelibs-dbg rather then kdelibs, kdebase-dbg rather then kdebase.
* After the crash a dialog should popup that allows you to catch such a backtrace.

I don't exactly remember what I was doing last when 4.0.1 crashed on me initially, but this problem remains after installing 4.0.2.  I have no desktop, toolbar, nada.  Luckily the terminal still comes up from when I was using it during that fateful session.

delete the `kde4-config --localprefix`/share/config/plasma-appletsrc file and try again.

@Aaron:
sdfaDeleting the mentioned directory helped.
I can now login to kde, and plasma crashes immediately AFTER the desktop, panel etc are loaded.

BTW if you cannot understand what I am typing: I am looking at a white box in the kde bug system, there is something wroong causing me to not see what I type.

@Sebastian:
I  I updated the whole of KDE.
What id did is: (in Yast):
Package-All Packages-update if nnewer version is available


Perhaps it is interesting to report I have a conflict in the package upgrade:
libqt4-dbus-1. Installed: 4.3.4-5.1
Wants to install: 4.3.1-2.3.4
So  Yast kept the old version.


And here is the backtrace, after I loaded a handpicked 90MB of debug stuff. Actually, everything was about 2GB
Let me know if you need anything more.
And: thanks for the fhelp! Lets make kde4 a success!

OK, I tried CTRL-ALT-Backspace to restart the X-session.
NoNow again plasma crashed before the desktop, pane etc was drawn
here is the backlog
ps this error where you cannot see what you type is not convenient! :-)

John: This is off-topic for this bug request, but the problem you mention about not seeing what you're writing in konqueror has been reported as bug #158607.

Updating today solved the problem.
Perhaps it was distro-related, due to a not correct combination of packages.
