Bug ID: 364364
Summary: KInfoCenter crashes after opening PCI tabfollowed by
Information about Power Management, and then closing
Product: kinfocenter
Version: 5.5.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: hubn...@gmail.com
Reporter: glitch...@gmail.com
Application: kinfocenter (5.5.5)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-21-generic x86_64
Distribution: Ubuntu 16.04 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Clicked PCI tab (Information about devices), Information about Power
Management, and then closed the application.
- Custom settings of the application:
To get better stacktraces (JavaScript JIT compiler appears to have hurt them),
I used QV4_FORCE_INTERPRETER=1 option. However, it crashes even without that
option.
The crash can be reproduced every time.
-- Backtrace:
Application: Centrum informacji KDE (kinfocenter), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
