Application: konsole (15.04.0)

Qt Version: 5.4.2
Operating System: Linux 4.1.3-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
I had two Konsoles open, ran a third via F2, closed all three consoles, then rapidly opened two via the desktop context menu.  I got two Konsoles as a result, even though there was the crash report and should have only been one.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
