Application: krunner (5.10.5) Qt Version: 5.9.1 Frameworks Version: 5.38.0 Operating System: Linux 4.13.0-16-generic x86_64 Distribution: Ubuntu 17.10 -- Information about the crash: - What I was doing when the application crashed: Opened krunner window with a configured shortcut (Alt+Space), began typing the word 'keyboard' immediately. Definitely saw the krunner window appear for a split second before it crashed. Not sure how much of the string I was typing made it in. Not 100% repeatable, but I've had it happen about once a day. As far as I can remember, I've been typing a different command each time. The crash can be reproduced sometimes. -- Backtrace: Application: krunner (krunner), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
