Version: (using Devel) OS: Linux Installed from: Compiled sources I'm using the Kubuntu pkgs for KDE 4.2 RC1 After login to system, the kded4 crashes with the following Backtrace!

(I found that shortcuts doesn't work)
If 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? This may be related/duplicate of bug 173163 Thanks :)
Yes, It seems it's about Phonon. *** This bug has been marked as a duplicate of bug 173163 ***
This failed assertion is different from #173163. Yours is failing because KSaveFile::open failed in the Hardware-Database. Please try the upcoming patch and tell me what error message you get.
Sorry, for late answer. After your comment i saw an upgrade for kde-base and kde-workspace on Kubuntu repository (Exprimental i think) I installed the dbg packages and wait for a crash, a few days age but no crashes happened during this time. :-/
I suspect that this error could happen when there is either no space left on a device or you don't have the right permissions to your own cache directory. Whatever it is, it shouldn't take down kded. So it needs more forgiving code in phonon/kded-module. I'll keep this open until that is finished.
I'm seeing kded4 crashes several times a day in Mandriva 2009.1. It looks to me like the one reported by Mehrdad Momeny. I will attach the crash report.
Created attachment 35382 [details] Crash report, Mandriva 2009.1
@Anne Wilson: your crash is unrelated to this report but to KPackageKit. Please open a new bug report against the "Kpackagekit" product and do not forget to add your KDE4 and packagekit versions. Thanks
Now done - bug #200464
Is this still valid in KDE 4.4?
Closing for lack of feedback. Please only reopen if this is reproducible in KDE SC 4.4.5 or later.
