Description Eike Hein 2017-09-08 07:01:24 UTC 
Application: plasmashell (5.10.90)
 (Compiled from sources)
Qt Version: 5.9.2
Frameworks Version: 5.38.0
Operating System: Linux 4.13.0-1.fc27.x86_64 x86_64
Distribution: "Fedora release 26 (Twenty Six)"

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

I was setting the tray entry for the GTK+ ibus panel from "Auto" to "Hidden" in the tray settings dialog. Upon "Ok" plasmashell crashes. This is 100% reproducable and has been happening for many weeks.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

>Qt Version: 5.9.2
Seems unlikely...

Can you see if your Qt has ab5d4c78224c9ec79165e8890e5f8b8e838e0709

it was added somewhere between Qt 5.9.1 and what will be Qt5.9.2
Comment 2 Christoph Feck 2017-09-25 20:54:41 UTC 
If you can provide the information requested in comment #1, please add it.
Comment 3 Eike Hein 2017-09-26 18:12:24 UTC 
[eike@ehl1 ~/devel/src/qt5 (5.9) 220K]$ git show ab5d4c78224c9ec79165e8890e5f8b8e838e0709
fatal: bad object ab5d4c78224c9ec79165e8890e5f8b8e838e0709

Guess not.
Comment 4 Eike Hein 2017-09-26 18:17:49 UTC 
Sorry, the above was wrong because I failed to cd into qtdeclarative properly.

But no, I don't have it there either.

New crash information added by DrKonqi

plasmashell (5.12.3) using Qt 5.10.0

- What I was doing when the application crashed: I change system tray setting for showing always an application.

- Unusual behavior I noticed: plasma pannel crashes
