Comment 1 Denis Kurz 2016-08-19 08:02:55 UTC 
This is still an issue with Apps 16.08, whether on Frameworks 5.23 or master.

Steps to reproduce:
1. Enable KRunner "Contacts" plugin
2. Search something in KRunner. Maybe this depends on your actual contacts, but for me, multiple calculations work, like "1+2+3"

Actual result:
KRunner crashes after pressing "3" for the above input.

Expected result:
KRunner says "6" (and does not crash)

Reproducible:
Always. Enabling or disabling any of the other plugins does not fix this behaviour, but disabling the Contacts plugin does.
Comment 2 Denis Kurz 2016-08-23 06:29:31 UTC 
Also, we might increase the chance if getting this bug fixed by assigning it to the akonadi people, since it seems to be triggered by the akonadi addressee serializer.

Re-assigning to Akonadi. It's trying to load QtWebEngine in response to a KRunner query which is stupid.

Comment 9 Denis Kurz 2016-09-01 17:01:37 UTC 
Isn't this just a linking error? Last time I checked, there was no call to QtWebEngine in the PIMContactsRunner, but it is linked against it somehow. So when the plugin is loaded by Qt, so is the QtWebEngine, which automatically triggers its initialize function.

Fixing the CMakeLists.txt might be enough to fix this.

On my system, /usr/lib/qt5/plugins/krunner_pimcontacts.so was built with -Wl,--as-needed. Thus if no part of the code uses a library, that library will not be linked against.

The full tree of linked libraries (omitting duplications) is given here - QtWebEngine is not among them:

My plugin isn't linked against WebEngine either, as your (really cool) script revealed. But then I don't understand how loading krunner_pimcontacts.so can possibly lead to QtWebEngine::initialize(). This is triggered deep withinQPluginLoader::instance() after all. Might this be an upstream bug?

For me the bug appeared with kde-apps 16.08.0. It's thus a regression from 16.04.3.

Git commit c25dcbd8852879a2f7ee102ef0f6555583b3dad7 by Daniel Vrátil.
Committed on 06/09/2016 at 13:33.

Don't link AkonadiContact from serializer plugins

This leads to crashes when the serializer plugin gets loaded from
non-GUI thread (like from KRunner), because AkonadiContact depends
on Qt5WebEngine, and even just linking Qt5WebEngine triggers static
globals initialization that crashes in non-GUI thread.
FIXED-IN: 16.08.1

krunner-20160911-214209.kcrash.txt

hmm I just got a very similar looking crash, are you sure this is fixed?

KF-5.26, Plasma.git master, KDE PIM 16.08.1
Comment 17 Andreas Sturmlechner 2016-09-12 06:29:51 UTC 
Checking back, the patch got in only after 16.08.1 tagging so this will be fixed in .2.

Comment 21 Weng Xuetian 2016-10-01 23:40:35 UTC 
IMHO, this need to be reopened since it's actually got reverted.

https://quickgit.kde.org/?p=kdepim-runtime.git&a=commit&h=acb496c86356d2b2fb6df23c108436db879a58ab

I wonder, if it is possible to make sure that krunner always load plugin in main thread? It is quite possible that any krunner plugin need such assumption.
Comment 22 Weng Xuetian 2016-10-02 03:52:27 UTC 
Sorry for the noise.

Looks like the reverted plugin right now is not relevant to contact runner. Can't reproduce it.

Comment 35 opensuse.lietuviu.kalba 2016-12-14 07:50:15 UTC 
I agree with comment #21
In duplicated bug 373371 was kdepim 16.08.2 
(and I can consistentlty reproduce by entering formula (without "=" as first character) in krunner, then jumping to begining of formula and adding more operation and moving with keyboard arrows or pressing Enter), 
thus is not fixed as expected.
