Version: (using Devel) OS: Linux Installed from: Compiled sources Steps to reproduce: Open systemsettings and go in Appearance -> Style -> Style. Change "Oxygen" with something else, for example "Plastique" and click "Apply". Current behaviour: No more desktop, no more plasma icon on top right, no more plasma bar on the bottom of the screen. Running "plasma &" from konsole fixes all these, except the top-right plasma icon. Is this top-right icon a separate problem?
The top-right icon ("cashew") is probably a different issue What KDE version are you using ? Do you get a Crash Handler dialog ? As you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks :)
I don't get a crash handler dialog, so I used gdb for the report. Below there is a copy-and paste of the debug session. I attach the result of rpm --query -a --queryformat "%{NAME} %{VERSION}\n" | sort >rpm.txt so you can see my packets and their version. If you need more infos, I'll be glad to provide them. I won't upgrade this system anymore until this is fixed, so you don't get confused by that. marco@suse-marco2:~> gdb /usr/bin/plasma `pgrep plasma` GNU gdb (GDB; openSUSE 11.1) 6.8.50.20081120-cvs Copyright (C) 2008 Free Software Foundation, Inc.

You have KDE4.2.1 according to the package list
I used the wrong rpm query. The correct one is: rpm --query -a --queryformat "%{NAME} %{VERSION}-%{RELEASE}\n" | sort >rpm.txt I attach the resulting rpm.txt file. These packets are updated very frequently (once a day or so), they are not the original 4.2.1. If there is some place to look for more trustable results, let me know (for example, some CHANGES, HISTORY, ... files hidden somewhere).

I don't know if it's a duplicate, but it doesn't crash anymore, so I set this as Verified.
Hello! Plasma 4 was replaced by Plasma 5 four years ago by the KDE community. In that time we have made great strides in stability and functionality. We are closing all Plasma 4 bugs as most of them are no longer applicable to the new frameworks Plasma 5 is built upon. If you could, please re-test with the latest version of Plasma 5, and submit a new bug to "plasmashell" if you continue to have an issue. Thank you!
