Bug ID: 319930
Summary: KDE Daemon Seg Faults when removing iwlwifi module (or
when reinserting module?)
Classification: Unclassified
Product: kdelibs
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: kded
Assignee: unassigned-bugs at kde.org
Reporter: peterbrowne at live.ca
Application: kded4 ($Id$)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Linux Mint 14 Nadia
-- Information about the crash:
Wifi ceased to work properly (dropped connection to AP) and KDE was slow and
sluggish - this occurs once every few days, maybe once or twice a week - so I
switched to tty1 to modprobe -r iwlwifi and reinsert, upon Alt+F7, KDE Daemon
returned a seg fault
Lenovo Y570(0862) Notebook Computer running Linux Mint 14 - current updates
were downloading and installing in the background
-- Backtrace:
Application: KDE Dæmon (kdeinit4), signal: Segmentation fault
