Bug 431608

Application: yakuake (3.0.5+)

Qt Version: 5.12.7
Frameworks Version: 5.71.0
Operating System: Linux 5.3.18-lp152.57-preempt x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.2"

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

- I'm a frequent user (daily) of Yakuake, mostly using it with 2-4 Tabs open, however, no Split Tabs.
- When I want to close my Tabs - either typing exit (in Bash), or via "Close Session" Mouse Menu Item - Yakuake crashes.

- Seems to be a Heisenbug though:

- If I have worked with multiple Tabs, side by side, and I'm starting to exit them one by one, crash happens 95 % of the time.
- If I use just one single Tab I mostly can exit Yakuake without seeing it crashing, so chance of crashing a single Tab is < 5 %.

- So the crash can be reproduced ALMOST every time.

The crash can be reproduced every time.

-- Backtrace:
Application: Yakuake (yakuake), signal: Segmentation fault
