Description p92 2018-01-06 08:13:44 UTC

Application: krunner (5.11.5)

Qt Version: 5.9.1
Frameworks Version: 5.41.0
Operating System: Linux 4.13.0-21-lowlatency x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
Sometimes when I call krunner using alt-SPACE, it crashes with signal 11.


The crash can be reproduced sometimes.

-- Backtrace:
A useful backtrace could not be generated

Comment 1 KaiMing 2018-01-08 16:03:57 UTC

I have similar issue on my machine as well, especially when I try to do some calculation from krunner.

I don't have such issue prior upgrading to KDE Plasma 5.11.5.

Qt version: 5.10.0
Kernel: 4.14.11-1-default #1 SMP PREEMPT Thu Jan 4 11:32:07 UTC 2018 (c36893f) x86_64 x86_64 x86_64 GNU/Linux
Distribution: OpenSUSE Tumbleweed version 20180106-0

I don't know how to generate a backtrace. It would be great if anyone can point me on this.

Comment 2 Kai Uwe Broulik 2018-01-08 16:19:18 UTC

Run "gdb krunner", then type "r" to run it. (kill krunner before you do that, there can always only be one instance of krunner running) Then make it crash and type "thread apply all bt" and paste the result of that here. Thanks.

Comment 3 KaiMing 2018-01-09 05:54:08 UTC

As per following your guide Kai Uwe Broulik.

Comment 4 Kai Uwe Broulik 2018-01-09 09:27:52 UTC

Thanks, so apparently it aborts because of "terminate called after throwing an instance of 'Xapian::DatabaseCorruptError'"

Now the question is, what is using Xapian here... Since 5.11 baloo is out of process, so it can't be it. Perhaps the Appstream runner? Aleix?

Comment 5 Luca Beltrame 2018-01-09 09:34:05 UTC

Can you test whether disabling the contacts search in KRunner still causes this problem?

Comment 6 Aleix Pol 2018-01-09 11:23:07 UTC

AppStream stopped using xapian a while ago.

Comment 7 KaiMing 2018-01-11 02:38:35 UTC

I can no longer reproduce the bug with similar method now. 

And it worked normally. The only thing that changed as I remember, is to remove my gmail account from kmail.

Is there any chances where upgrading my distro without rebooting my laptop causes this issue? As I suspend my laptop for a few days sometime, even after update.
