Logs? Errors? Also please post the output of 'pacman -Qm'

Hi. Nothing to show up... after launch in terminal I have nothing additional.
Maybe it is related with krunner issue  FS#46291

Look in the journal (as root). And what's the output of 'pacman -Qm'?

Can you try with an application that doesn't use baloo? (eg. kwrite), and then post the journal output if it crashes.

You should mention that it works with baloo 5.13, so the devs know that this was introduced in 5.14
Comment by Tomasz Przybył (FadeMind) - Monday, 14 September 2015, 10:51 GMT
Done.
Comment by Antonio Rojas (arojas) - Wednesday, 16 September 2015, 06:11 GMT
Please try baloo 5.14.0-2
Comment by Tomasz Przybył (FadeMind) - Wednesday, 16 September 2015, 06:15 GMT
Nothing changed.

Try a reboot or KDE relaunch. It's fixed.
Comment by Tomasz Przybył (FadeMind) - Thursday, 17 September 2015, 06:15 GMT
After reboot I had the same issue - segfault.
Comment by Antonio Rojas (arojas) - Saturday, 19 September 2015, 22:39 GMT
Can you try the workaround in https://bugs.kde.org/show_bug.cgi?id=352365#c7 to see if it works for you? We need to get this out of testing and fixing this doesn't seem to be high priority for upstream.
Comment by Tomasz Przybył (FadeMind) - Sunday, 20 September 2015, 05:17 GMT
STEPS

As normal user:

1. disable search in baloo settings.
2. clear history

Repeat this steps as root.

Finally re-enable searching.
No more segfaults dolphin as root.
Thanks for tip.
