Bug 394320

Summary: Krunner crashed after attempting to open it with alt-F2
Product: [Plasma] krunner Reporter: shout
Component: generalAssignee: Kai Uwe Broulik <kde>
Status: RESOLVED DUPLICATE    
Severity: crash CC: epost.kde, shout
Priority: NOR Keywords: drkonqi
Version: 5.12.5   
Target Milestone: ---   
Platform: Neon   
OS: Linux   
Latest Commit: Version Fixed In:
Sentry Crash Report:
Attachments: New crash information added by DrKonqi

Description shout 2018-05-16 10:57:41 UTC 
Application: krunner (5.12.5)

Qt Version: 5.10.0
Frameworks Version: 5.46.0
Operating System: Linux 4.13.0-41-generic x86_64
Distribution: KDE neon User Edition 5.12

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

Attempting to open krunner with alt-F2

- Unusual behavior I noticed:

krunner immediately crashed. It not fails to open - alt-F2 returns no response. Backtrace shows a segfault.

I had restarted plasmashell just prior to the krunner crash, as the shell appeared to be crashing - icons all disappeared from the Panel, replaced by empty white blocks. This has happened numerous times over the past few days.

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

New crash information added by DrKonqi

krunner (5.12.5) using Qt 5.10.0

- What I was doing when the application crashed:

Listening to a podcast using VLC.

- Unusual behavior I noticed:

The icons on the main panel were suddenly replaced with large empty blocks and all panel functionalty ceased (it had crashed, in other words). I attempted to open Krunner with alt-F2 to restart plasma, which did open. However, upon beginning to type in the input field it crashed.

This is exactly what happened yesterday (see above). I am attaching this to demonstrate that this is a reocurring issue and to provide a further backtrace which may hopefully be of some help.

-- Backtrace (Reduced):
