Description Boyuan Yang 2016-09-27 15:18:51 UTC 
Application: plasmashell (5.7.4)

Qt Version: 5.6.1
Frameworks Version: 5.25.0
Operating System: Linux 4.6.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (stretch)

-- Information about the crash:
- What I was doing when the application crashed:
1. Use alt+f1 to open application launcher;
2. Type a few characters, i.e., "n" and "i". The typing speed must not be too fast nor too slow. Maybe 1.5 char/second is enough.

That's all. The plasmashell would freeze for 2 seconds and then crash (SIGSEGV).

The crash will not reproduce 100%, but the rate is pretty high. If no crash happens, simply use backspace to clear the searching area and try again.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

plasmashell (5.10.90) using Qt 5.9.1

- What I was doing when the application crashed:

The same story as in Bug 369430
likely to benefit from this report is not ... but who knows

Screenshot

One way to reproduce the bug shown in the screenshot.
It happens almost always
Comment 25 Alexander Mentyu 2017-08-28 09:21:58 UTC 
There is a Kicker menu on the screenshot - not Kickoff.

Cannot reproduce this bug both in Kickoff and in Kicker in:

Distribution: KDE neon Developer Edition Unstable Branches
KDE Plasma Version: 5.10.90
KDE Frameworks Version: 5.37.0
Qt Version: 5.9.1
Kernel Version: 4.10.0-32-generic
Comment 26 Boyuan Yang 2017-09-04 14:25:56 UTC 
I can confirm that after upgraded to Plasma 5.10 and Qt 5.9, this problem disappeared.

Just wondering if we could locate the problem and have it fixed in LTS version.
Comment 27 Christoph Feck 2017-09-19 22:00:02 UTC 
Are you saying that you can still reproduce this crash in Plasma 5.8.7 (with the same steps and backtrace), but not in Plasma 5.10? I see no code changes in the runner model, so this bug was not specifically addressed for the newer Plasma version.

Important detail from bug 380885 comment #15:

"I was not able to reproduce the bug with 'Flatten menu to a single level' settings applied."
Comment 31 David Edmundson 2017-10-05 12:48:04 UTC 
I think it's gone away with Qt5.8
David F and others did some delegate cleanups.

It did with TaskManager, (just then we had another bug in it)

David, do we have an upstream ticket? Bug 386500 is with Qt 5.9.2, and is the same backtrace.

Comment 46 David Edmundson 2019-02-21 11:15:49 UTC 
FWIW, I made a change in 5.15.0 

commit 9371a7c96d4722b93b49b18df7b21780f2a9ad38

Effectively we didn't pass Qt's model test, now we do.

Even though I couldn't reproduce this crash as-is, I think there may well have been a correlation and this could have been our bug after all.
