Description Oded Arbel 2020-01-01 13:21:54 UTC
Application: yakuake (3.0.5+)

Qt Version: 5.12.4
Frameworks Version: 5.66.0
Operating System: Linux 5.3.0-25-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
using CTRL+d to log out of one of the tabs in Yakuake, with the purpose of closing that tab.

Using KCI unstable yakuake 19.12.0+p19.10+git20191226.2305-0 and konsole-kpart  4:19.12.0+p19.10+git20191226.2307-0

The crash reporting assistant suggested a lot of duplicates for this behavior, but all I saw were fixed in KDE/Qt 4. This is a new one for me, and I haven't seen it before, so I'm guessing its a regression in current git master.

The crash can be reproduced sometimes.

Comment 1 Christophe Marin 2020-01-02 13:51:27 UTC
Confirmed and reproducible.

Test #1:
- Open different terminal tabs
- Click in the konsole window
- CTRL-D closes the terminal, yakuake is still running

Test #2:
- Open a couple tabs
- Click on the terminal tab bar
- CTRL-D
- Crash with the same bt as the reporter:

Noah's crash report with backtrace

I can confirm this as well. I'm not sure what happens or how long one needs to wait, but this crash doesn't seem to happen to recently opened instances of Yakuake.

New crash information added by DrKonqi

yakuake (3.0.5+) using Qt 5.14.1

- What I was doing when the application crashed:

Accidentally clicked on the close button in yakuake while it had maybe two or three active tabs, and it crashed.

Comment 4 JanKusanagi 2020-04-22 20:34:04 UTC
I get a crash that looks mostly like "Thread 1" in the original report, and I can reproduce consistently after a second of launching Yakuake with this simple procedure:

- Press the shortcut to show Yakuake.
- Right-click somewhere in the "console area" to get the context menu.
- Dismiss the context menu by clicking in any other empty area of the "console area".
- Press Ctrl+D to exit the Bash shell, which closes the only tab, and crashes Yakuake.


Operating System: Mageia 8
KDE Plasma Version: 5.18.3
KDE Frameworks Version: 5.69.0
Qt Version: 5.14.1

Yakuake reports itself as "Version 3.0.5+".
The "package version" is 20.04.0, same as Konsole.

Comment 10 Ricardo J. Barberis 2020-05-02 18:09:52 UTC
Happens to me too, seeminlgy randomly.

I didn’t experience crashes yesterday nor today but I'm being careful not to leave any text selected with the mouse (X selection) before closing the session, which was my gut feeling.

My second difference between crashes/no crashes would be a secondary display connected, which I didn't have yesterday or today.

Application: yakuake (3.0.5+)

Qt Version: 5.14.2
Frameworks Version: 5.69.0
Operating System: Linux 5.3.0-46-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
- What I was doing when the application crashed:
closed a couple of tabs using ctrl+d (in some tabs I did multiple ctrl+d in a row in order to exit sub-shells and ssh sessions before closing the local shell/tab). Had like eight tabs open and wanted to reduce it to one tab. ctrl+d frequency was very fast.

The crash can be reproduced sometimes.

Ah, I missed that amongst all the backtraces :)

Thanks for pointing it up and let's hope a solution is found soon.

Different contributors make improvements to yakuake, see https://cgit.kde.org/yakuake.git/log/

This crash is not easy to investigate, because it actually crashes in the XmlGui framework used by the Konsole part.
Comment 19 JanKusanagi 2020-05-06 19:18:55 UTC
I just found out, thanks to certain updates in a Debian Sid machine, that I can't crash Yakuake 20.04 if it's run/built with Frameworks 5.62 (what Debian Sid has ATM). At least, not following my method that crashes every single time under Mageia with KF 5.69: https://bugs.kde.org/show_bug.cgi?id=415762#c4

Considering other bugs in Konsole related to recent changes in KBookmarks, could that be what's breaking Yakuake too? If so, I've read about some changes in KF5.70 that might help...

Relax...

And to be fair, I'd say most people (me included) didn't start to get this crash until ~2 weeks ago.

In KDE Neon worked fine until 2 weeks ago, now is pretty unusable.

Comment 22 kjift14 2020-05-15 00:02:18 UTC
Same crashing behaviour on Arch Linux and Artix: In about 1 of 5 cases of closing a yakuake tab, the complete application terminates and has to be restarted.

Noteworthy on my Arch system:

Qt 5.14.2-2
Operating System: Linux 5.6.11-arch1-1
Distribution: Arch Linux
Yakuake version: v3.0.5.1.g4d89450-1

This yakuake-git version was compiled from AUR in april 2018 and not updated since then. Though, the crashes started some two months ago (?), so it cannot be an issue of yakuake (alone).

Indeed this can still be reproduced even after applying https://cgit.kde.org/konsole.git/commit/?id=fdfae25665731882687da8721e58c3c56a3babf8

(this is not the 'Set Encoding' crash, I am avoiding that context menu entry quite successfully by now)

Git commit d40e3c72f2ad9262d6028bc62bc2837067b824a0 by Kurt Hindenburg, on behalf of Maximilian Schiller.
Committed on 29/05/2020 at 12:00.
Pushed by hindenburg into branch 'release/20.04'.

Fix konsolepart segfault when closing after showing context menu

Assign the _view as the parent to the KXMLGuiFactory because the
factory is referencing the view widget as its associated widget. Since
the TerminalDisplay gets destructed first this is now a dangling
pointer. If the view is set as the parent the factory gets cleaned up
correctly.  Also cleanup the created clientBuilder after destruction
because it can't have a parent and would probably leak memory.
FIXED-IN: 20.08.0

I can confirm that since Mageia rebuilt Konsole with those 2 patches, I can't crash neither Yakuake nor Dolphin's terminal the way I used to (and Yakuake has been running without issue for over 24 hours).

THANKS!
Comment 31 Ricardo J. Barberis 2020-05-30 19:16:49 UTC
I applied this patch on top of konsole 20.04.1 and so far I haven't been able to make yakuake crash.
