and started automatically, and sometimes (after login) it crashes without any crash report, and i have to start it manually! (I found that shortcuts doesn't work)

Comment 1 Dario Andres 2009-01-17 12:42:16 UTC

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 :)

Comment 2 Mehrdad Momeny 2009-01-17 18:45:32 UTC

Yes, It seems it's about Phonon.

*** This bug has been marked as a duplicate of bug 173163 ***

Comment 3 Matthias Kretz 2009-01-18 13:59:50 UTC

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.

Comment 4 Mehrdad Momeny 2009-01-23 09:35:27 UTC

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. :-/

Comment 5 Matthias Kretz 2009-01-23 12:07:26 UTC

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.

Comment 6 Anne Wilson 2009-07-16 13:48:22 UTC

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.

Comment 7 Anne Wilson 2009-07-16 13:49:15 UTC

Created attachment 35382 [details]
Crash report, Mandriva 2009.1

Comment 8 Dario Andres 2009-07-16 17:29:48 UTC

@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

Comment 9 Anne Wilson 2009-07-16 18:41:16 UTC

Now done - bug #200464

Comment 10 Myriam Schweingruber 2010-02-09 23:06:00 UTC

Is this still valid in KDE 4.4?

Comment 11 Myriam Schweingruber 2010-07-19 14:50:13 UTC

Closing for lack of feedback. Please only reopen if this is reproducible in KDE SC 4.4.5 or later.
