            Bug ID: 347710
           Summary: Plasma crashed when I closed Okular from the taskbar
           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: juanalberti at gmail.com

Application: plasma-desktop (4.11.11)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Linux Mint 17.1 Rebecca

-- Information about the crash:
- What I was doing when the application crashed: I had two Okular windows
opened, I wanted to close one of them, I right-clicked on the taskbar and when
I attempted to close it, Plasma crashed and restarted. I tried to repeat the
crash but I couldn't...

The crash does not seem to be reproducible.

-- Backtrace:
Application: Shell de escritorio Plasma (plasma-desktop), signal: Segmentation
