            Bug ID: 343358
           Summary: plasmashell crashed after killing firefox
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: vit at pelcak.org

Application: plasmashell ()

Qt Version: 5.4.0
Operating System: Linux 3.18.3-1-desktop x86_64
Distribution: "openSUSE 20150125 (Tumbleweed) (x86_64)"

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

I spotted that plasma has problems working with Firefox/Thunderbird/LibreOffice
applications.

After using Firefox for a while, plasma started to be unresponsive. For example
decreasing volume by scrolling over kmix icon in systray or cklicking on that
icon didn't work. So I switched to terminal and killed FF. Then plasmaskhell
crashed and drkonqui was started.

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