            Bug ID: 337197
           Summary: CPUFreq Utility by Fl@sh causes crash
    Classification: Unclassified
           Product: plasma
           Version: 4.11.10
          Platform: Mint (Ubuntu based)
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: plasma-bugs@kde.org
          Reporter: jlinkkai@gmail.com

Application: plasma-desktop (4.11.10)
KDE Platform Version: 4.13.2
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Linux Mint 17 Qiana

-- Information about the crash:
- What I was doing when the application crashed:

I simply go to add the widget to my panel and it causes the whole environment
to break momentarily. As the title suggests, this is caused by adding CPUFreq
Utility to my panel. Could be an old piece of software so perhaps it's my fault
for trying to use it past its time.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
