Description Jonathan 2009-02-14 14:19:28 UTC
Version:            (using KDE 4.2.0)
OS:                Linux
Installed from:    Unlisted Binary Package

System Settings always crashes when I want to navigate to the Accessibility menu. I've just noticed this behavior, but I don't know if this happened before. It might just have been the first time today that I tried to enter the Accessibility part of System Settings.

I'm using Arch-Linux with 32-bit KDE 4.2.0.

Comment 1 Konstantinos Smanis 2009-02-15 19:55:27 UTC
Does it crash when running it using "kcmshell4 kcmkttsd"?
Comment 2 Dario Andres 2009-02-15 23:17:01 UTC
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 :)
Comment 3 Konstantinos Smanis 2009-02-16 19:11:32 UTC
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.
Comment 4 Jonathan 2009-02-16 23:40:34 UTC
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
https://bugs.kde.org/show_bug.cgi?id=161497

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