Bug 184310

Does it crash when running it using "kcmshell4 kcmkttsd"?

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? 
You may need to recompile the packages in order to get debug symbols, (or install the -debug packages if you are using KDEmod)
Thanks :)

I am too using Arch-Linux with 32-bit KDE 4.2.0, but can't reproduce this.. You should provide more information maybe on how and under which conditions the crash occurs.

Using "kcmshell4 kcmkttsd" also crashes, with almost the same backtrace (there are just some threads missing)

I've had KDE running now for 12 days and after restarting today I noticed that I can access the ktts-settings again.
So it took me now almost 2 hours to find out how to reproduce the bug with a fresh start, at I could at least partly reproduce it on my notebook.

1. Deinstall all ktts-talker libraries (festival, flite, etc)
2. Open any pdf (probably any kind of document works) with Okular
3. Select Tools -> Speak whole document
4. This always ends in a crash (Backtrace #1)
5. Repeat until "KTTS not Configured" shows up
6. Selecting "Configure" ends in a second crash (Backtrace #2)
7. After this second crash it's not possible anymore to open ktts-settings (Behavior as in opening-description)

On my laptop I could only reproduce the first crash. But as my laptop is a dual core and we have some a couple of different threads involved here this might be the reason.
On my desktop I can always reproduce this with a fresh kde-start. I had to repeat step 5 up 1-5 times until the "KTTS not Configured" dialog showed up. Again I think this might be because of a different processing of the threads.

Restarting KDE brings back the normal behavior and I can open the ktts-settings. If I have at least one speaker-library installed there are no crashes at all. When there's no configured speaker for ktts, the available speaker-library gets automatically chosen and speaking starts.

I hope you are able to reproduce this behavior, if I can provide any further information I will try to do so.
But as compiling KDE with debug enabled needs some time it would have to wait until next month.
But I think the provided Bugtraces aren't too bad. There's not a single "(no debug symbols found)" message and except of some non-KDE function-calls all function-names are given.

This looks like the bug in: 161497

and when I run the command "kcmshell4 kcmkttsd" it crashes immediately and this is the backtrace:
