Application: krunner (5.5.4) Qt Version: 5.6.0 Operating System: Linux 4.5.0-0.rc1.git2.1.fc24.x86_64 x86_64 Distribution (Platform): Fedora RPMs -- Information about the crash: - What I was doing when the application crashed: I had just updated the system and rebooted and started "X". This limitation on the amount of data that can be provided here is really stupid. I have a core file and probably the output of gdb but HOW do I provide this? After the bug is created? That would be a good idea but if this tool refuses to create a bug, I'm stuck. - Unusual behavior I noticed: none - Custom settings of the application: Nothing specific comes to mind The crash can be reproduced sometimes. -- Backtrace: Application: krunner (krunner), signal: Segmentation fault Using host libthread_db library "/usr/lib64/libthread_db.so.1".

Created attachment 96934 [details] core file from this crash Hi, Could I get some indication as to just when this problem will be looked at please? I seem to get them frequently. Thanks, George...
Can you still reproduce this? Can you maybe show us how to?
This problem just happens during "normal" processing. I had just updated my system and rebooted and issued a "startx" command to get the GUI up. It just happens. I do have 99+% of all the packages in "dnf group list" installed. Can "we" instrument the crash somehow? Set a "trap" for the crash? I'm all ears. George...
Aleix, I just verified that the problem still exists. It does. This a Fedora 24 x86_64 system in a "VirtualBox VM". What I do is ssh into the VM after boot. My default run level is 3 so I can do command like stuff and start X if I need to. From the ssh session I can start "X" so I could do tracing or whatever and capture the output to send you if you have things you want me to try. Regards, George...
Created attachment 96982 [details] gzip'd flat file with package groups install logic After the install of F24 I run "dnf -y upgrade" and then this script and reboot.
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!
Andrew, I haven't seen this in some time... Let's close it, ok? Best regards, George...
Thanks for the update!
