I really don't understand your idea. How can I reinstall KWin themes if the interface for managing KWin themes crashes every time?

Current KWin theme is standard Oxygen, if it matters, but I don't think that it does matter.

did you already tryed to open the terminal & type
kwin --replace
?

The idea behind this is, you might have installed & currently running a theme not usable by kwin
if you replace this theme - with a usable by kwin - kwin possibly can start again

last thing on idea i have is
open synaptic
look for wat is installed
try to remember what you had installed before the crash
all your files about the manager + the theme you want
mark 'em for reinstall
reboot
look what happend

this happens rearly but it is possible that the new theme wrote something
between ore at the end of a line in one ore some of the needed scripts
they were installed correctly
(maybe) they had changed
but they are not listed as broken
so
if nothing helps
try the reinstall

please let me know if something works for you

l.t., are you a bot?

I restarted KWin; I restarted the computer; I removed all themes that I could remove through package manager; I removed certain folders inside ~/.kde. You are writing non-relevant ideas. KWin is started and runs well, the problem is that KWin's configuration component can't start.

so why don't you try to reinstall it ?

if you think so, I'll get my a** outa here

good luck anyway - maybe there is another person with different ideas

@greatperson: Please try moving ~/.kde4/share/config/kwinrc elsewhere. This should reset KWin back to the KDE default, which is Oxygen and should function.

If the issue still persists, can you get a backtrace of the System Settings or KWin crashes?

Moved away ~/.kde/share/config/kwinrc, restarted kwin, nothing changed.
Moved away everything like ~/.kde/share/config/kwin*rc, restarted kin, nothing changed.

These are files I have (and I tried to remove) there:
kwin_dialogsrc
kwin_rules_dialogrc
kwin.eventsrc
kwin.notifyrc
kwindeKoratorrc
kwinplastikrc
kwinqtcurverc
kwinrc
kwinrulesrc
kwinskulpturerc

This is System Settings' backtrace after I try to enter Workspace Appearance having default settings (but having installed themes):

Try removing smaragd

Actually uninstall _all_ third party window decorations, including, but not limited to

bespin
crystal
dekorator
oxygen-transparent
oxygen-appmenu (if such exists)
qtcurve
smaragd
skulpture

Hmm. Really, deleting Smaragd helped. I feel stupid because I haven't noticed that it was installed through package manager.
But anyway it's sadly that I needed to guess it and couldn't find out the location of problem through interface.

So, haven't you noticed that the piece text was repeated for every installed decoration, including even those with «kde3_» prefixes?

Hey Greatperson, are you using kde 4.9 from kubuntu backports ppa? If yes, go to synaptic and delete libkdecoration4 4.8.x.
Thats goes delete qtcurve too, but is the price. The segfault is caused by this library not compatible with kde 4.9, and dependency of qtcurve
Excuse my poor english.
