Description Vangelis 2016-11-22 13:27:27 UTC 
My installation:
------------------------------------------------------------------------------------------------
KDE Neon User Edition.
Latest updates up until today (22 November 2016, 13:20 UTC).



What happens:
------------------------------------------------------------------------------------------------
krunner suddenly started crashing. When the crash occurs for the first time after I login, I get the following two-stars backtrace:


Application: krunner (krunner), signal: Segmentation fault

The following missing symbols are reported, but I couldn't find a package to install them:
------------------------------------------------------------------------------------------------
/usr/bin/krunner
/usr/lib/x86_64-linux-gnu/libQt5Core.so.5
/usr/lib/x86_64-linux-gnu/qt5/plugins/krunner_windowedwidgets.so

On every subsequent run, krunner crashes with a segfault, but no backtrace shows in Dr. Konqi.




What changed since the time that krunner was working:
------------------------------------------------------------------------------------------------
Until yesterday everything was working fine.

The only change today is that the following packages got upgraded:

What solves the problem:
------------------------------------------------------------------------------------------------
Disabling the "Windowed widgets" krunner plugin prevents the crashing.
Comment 1 Vangelis 2016-11-22 13:36:02 UTC 
I just found the missing debugsymbols that I needed to get a three-stars backtrace. It was in the package 'plasma-workspace-dbg:amd64 (4:5.8.3-0neon+16.04+build57)'.
