Description ventyl86 2016-09-02 06:51:07 UTC

Application: kded4 (4.14.21)
KDE Platform Version: 4.14.21
Qt Version: 4.8.7
Operating System: Linux 4.4.14 x86_64
Distribution (Platform): Slackware Packages

-- Information about the crash:
- What I was doing when the application crashed:
Firefox was playing video via HTML5 when Kopete played sound event on incoming message. The event was played successfully but KDE launched "Removed sound device" dialog, kmix disappeared and appeared again and something crashed. This is usual behavior after login.

- Custom settings of the application:
Sound is configured that alsa is directly accessing the sound card and pulseaudio is configured as passthrought to alsa for everyone who uses it.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!

Comment 2 ventyl86 2018-11-02 08:51:42 UTC

Due to pervasive and highly disturbing nature of the bug - KDE with kded crashed is mostly useless for anything which runs behind curtains including power management - I stopped using KDE completely some time after reporting this bug.

There was no response here and I was not able to work around it by myself.

Comment 3 Andrew Crouthamel 2018-11-02 22:36:21 UTC

Thanks for the update!
