            Bug ID: 342044
           Summary: USB Devices Causing System Freeze
           Product: kdelibs
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: shawn at strongerforyou.com

Application: kded4 (4.14.3)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: Linux 3.17.6-200.fc20.x86_64 x86_64
Distribution: "Fedora release 20 (Heisenbug)"

-- Information about the crash:
- What I was doing when the application crashed:
Nothing out of the ordinary.  It's happened while just web browsing, while just
emailing, while just using an ssh in konsole
- Unusual behavior I noticed:
The mouse and keyboard (usb logitech) become unresponsive, then the entire
system becomes unresponsive.  Unplugging the devices from USB free the load and
restore control.  This only started after the most recent kde update via yum
(fedora)

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
