Bug ID: 358372
Summary: KDE System Settings Crashed applying changes to
Trackpad configuration
Product: systemsettings
Version: 5.4.1
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: emeraldd.ch...@gmail.com
Application: systemsettings5 (5.4.1)
Qt Version: 5.4.2
Operating System: Linux 4.2.0-25-generic x86_64
Distribution: Ubuntu 15.10
-- Information about the crash:
- What I was doing when the application crashed:
I was attempting to adjust the sensitivity and tap delays of the track pad and
system settings crashed. I experienced this crash twice, once with no
immediately discernable trigginer action and the second time when hititng the
apply button. Oddly enough, it would appear that the changes have actually
been applied to the system.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
