Description Serkan Barut 2015-11-30 11:48:30 UTC

Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.3.0-2-default x86_64
Distribution: "openSUSE Tumbleweed (20151128) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

Started computer and entered login credentials, while wating for desktop to load(without any user activity) crash windows appeared.

- Unusual behavior I noticed:

Very slow loading of desktop(due to heavy io activity of tracker and baloo during KDE startup. confirmed via iotop.)

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), 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!
