--- Comment #1 from Peter Wu <peter at lekensteyn.nl> ---
Can confirm this, on exiting a Konsole window through Ctrl+D, a crash has
occurred.
In case it is relevant, a few minutes before this event, some windows were
closed via Alt+F4. Backtrace and disassembly follows.

Distribution: Arch Linux x86_64
qt5-base 5.7.0-3
konsole 10.08.2-1

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