            Bug ID: 361916
           Summary: Maximizing app crashes KDE
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash

          Assignee: unassigned-bugs at kde.org
          Reporter: ineedbettername+kde at gmail.com

Application: plasma-desktop (4.11.11)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.19.0-32-generic x86_64
Distribution: Linux Mint 17.3 Rosa

-- Information about the crash:
- What I was doing when the application crashed:
I was attempting to maximize the linux Steam client, to play some vidya games.
I must have misclicked or something, because the whole KDE crashed.

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