I just upgraded my KDE 4.8 into 4.10.2 few days ago. All good and so fast but there is one problem. I can't open Workspace Appearance at System Settings. Always make System Settings crash. So now I can't change my KDE theme. Here is backtrace from KDE Crash Handler. I have sent bug information too from here. What should I do for fixing this? What patch I should download? I wanna change my KDE appearance now

ADDITION
Ah yah, KDE Crash Handler also give me message: Executable: systemsettings PID: 5549 Signal: Segmentation fault (11)

Just a comment that it works fine for me on Kubuntu 12.20 with KDE 4.10.2

does it run as a new user?

if so there's probably a rc file from 4.8 that 4.10 does not like

If you have upgraded your KDE packages to 4.10, please make sure that all packages required have been updated, in particular those concerning Oxygen and KWin. I suspect a binary incompatibility between the Oxygen Style library and the Oxygen KWin style in this case.

I am using Ubuntu 12.04. What rc file in specific, Sir? Should I delete it? Thank you.

The file in question would probably be "kwinrc" or "oxygenrc", however I would recommend checking the packages first.

I have renamed kwinrc into kwinrc~ and restart, but my System Settings still crash when open Workspace Appearance. Same result with oxygenrc. Even I deleted oxygen-gtk from my system. What should I do then? Thank you

A likely reason for this crash, as has been said, is that you forgot to upgrade a package or two, and still have the 4.8x versions installed. You should check for that in your package manager and update those packages. If you write what distribution you use, people might even know which packages that might be.

Wow, KDE developer? Thank you, Sir. I am using Ubuntu 12.04 now. Oh, so the roblem is upgrade incomplete? Thank you. I will check again.

Heh, I'm just writing a small application, while e.g. bcooksley is running the whole infrastructure
Also there's no need to call anyone "Sir", we're cool.

In ubuntu, I suspect you should look at the kde-style-oxygen and kwin-* packages specifically.

Cheers

Okay, okay, solved. Scummons, I have take Kubuntu PPA again in Synaptic and do update index, ah yes my kde-style-oxygen was old. So, I upgrade it. And wow, my System Settings at Workspace Appearance works well again! No crash anymore! Works like charm!

Let me know please, from where you know if I should upgrade kde-style-oxygen? It is one package between hundreds! From where you know I have forgotten it? Let me know, I want to learn.

Well, Ben guessed it first
I'd say there's two hints: it's one of the few packages which are seperate and belongs to the module you were opening, and also your backtrace tells "/usr/lib/liboxygenstyle.so.4" to be the crash location, which is a strong hint that something is wrong with the oxygen style.

Cheers,
Sven

As a general rule, KDE packages should all be upgraded in line with each other, and should always come from the same base repository, to prevent any binary compatibility problems.

In this case, the crash was caused by a binary compatibility in liboxygenstyle and kwin_oxygen.

I believe if I ask developer, I will get full satisfaction Better ask developer for bug. It is the reason why I paste the bug information here. So, thank you, Developer. Thank you all here.

Administrators count as developers too, of course.
