Bug 372743

Application: konsole (16.08.2)

Qt Version: 5.6.1
Frameworks Version: 5.27.0
Operating System: Linux 4.8.6-201.fc24.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

Initially I had a single konsole window with multiple tabs, using the mouse I then dragged one and released it over the plasma desktop, so that two konsole windows were present.  Then on the new window (with only one tab), I created yet another tab (CTRL-SHIFT-T).  A while later, using the keyboard shortcuts (SHIFT-RIGHT and SHIFT-LEFT), I was switching between multiple terminal tabs on the second konsole window.  Konsole crashed and as expected both konsole windows disappeared, since IIUC, one konsole process owns both windows.  All terminals sessions were lost due to the crash.

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