            Bug ID: 351267
           Summary: Plasma crashed when closing a iceweasel window and
                    changing the workspace
           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: mmestre at gmail.com

Application: plasma-desktop (4.11.13)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.1 (jessie)

-- Information about the crash:
- What I was doing when the application crashed:
I had three iceweasel open windows. One of them has only a youtube tab, playing
at fullscreen. The crash happened exactly after I closed that particular
iceweasel window, and move to another workspace using a custom keyboard
shortcut.
I dunno if those are related, but I wasn't doing nothing more particular than
that.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
