krunner segfaults on current 64 bit with kde plasma 5 desktop


I have been running current 64 for about two months, and found it very stable. I was bored, so I decided to install Aliens latest KDE from ktown repo.

I usually run xfce, and have not used KDE for some time, so I decided to look through system settings, and see what has changed.

Initially krunner worked as expected. Now it segfauts. The input bar appears with either Alt + F2 or Alt + space. The first keystroke of any application I may want to launch causes a segfault. I can click on the down arrow to select from a list, however it segfaults as soon as I select an application from the list.

To try and resolve the problem I have reinstalled krunner. This did not help.

I logged into a different user, and krunner is working on that user.
This led me to think, possibly some corruption in the many areas KDE stores things, ie cache. I deleted ~.kde directory. No change there.

I also set /tmp up to clear on shutdown. I did get krunner to work a few times after the change to /tmp, and I thought I had fixed the problem, however, it has returned. No amount of booting has altered the problem. I did verify /tmp is cleared.

I have current updated to the Dec. 6th updates. KDE is from ktown latest.

Is anyone else experiencing krunner segfaults?

Suggestions on what to do, or try next?

Following is the output from a failure from first keyboard character input.
Code:
bash-4.4$ krunner &
[1] 2225
bash-4.4$ org.kde.plasma: unversioned plugin detected, may result in instability
KCrash: Attempting to start /usr/bin/krunner from kdeinit

QSocketNotifier: Invalid socket 8 and type 'Read', disabling...
QSocketNotifier: Invalid socket 37 and type 'Read', disabling...

This is a sample segfault from using the down arrow, and a single click on an application.

Check and make sure you didn't miss something that was added. I did a couple of weeks ago and I couldn't even start kde. XFCE worked though. I am running current and use krunner often. I haven't had a problem....yet.

I usually run slackpkg install-new. I have seen threads where new packages were missed. Just to be sure, I just ran the usual four commands. Nothing was added by install-new.

Quote:
root@duelie:~# slackpkg install-new

Looking for NEW packages to install. Please wait... DONE

No packages match the pattern for install. Try:

/usr/sbin/slackpkg upgrade|reinstall
Thank-you for the thought though.

just to confirm, you do have this installed?

if you don't know about this, read the comments section from alien's Plasma October batch

No, I did not have icu4c-compat installed. I have to assume it did not download with the rest of KDE5. I have installed it, and so far, so good. I was able to launch Thunderbird and Chromium from krunner.

However, I am not going to mark this thread solved for a few days. My experience with this problem was, some times it fails, some times it may work for a few tries. In my initial post I mentioned it worked for another user on this system. It did on my first try. Yesterday I switched users, and it was failing there too.

I read through the Aliens blog comments section. Thank-you for the help.

I did see I am not the only one having issues with krunner.

Running 'slackpkg install-new' will NOT update Alien Bob's ktown. It will only update "new" Slackware64-current packages. You need to follow the instructions in the ktown README.

Using slackpkg+ would be an alternative to maintained ktown. The recommend method is to follow the README.

After several days of use, and adding the icu4c-campat package, krunner is not segfaulting any more.

Thank-you for all those who helped.
