[Testing Update] 2021-05-12 - Kernels, KDE Frameworks, Plasma, Systemd, Mesa, LibreOffice, KDE Gear Mobile, FF, TB

Ever since Frameworks got updated to 5.82, it seems trying to search files via Dolphin outside of one’s home folder causes kdedinit5 errors like inotify_add_watch(/etc/NetworkManager/system-connections) failed: (Permission denied) and QWidget: Cannot create a QWidget without QApplication, resulting in filenamesearch. to dump core. Seems to be another oopsie in KDE’s end that people are already reporting on their bug tracker. Just so you know Edit: To clarify, this crash occurs with any …

so i guess i’ll wait?

[Fabby]

@linub

so i guess i’ll wait?

That’s a coredump, so yes, wait for that to be solved.

While waiting, you can do the following:

pamac install mlocate
sudo updatedb
locate NameOfFileYouWantToLocate

and after the bug gets fixed:

pamac remove mlocate

[linub]

i just checked after this last update,and the issue hasn’t been fixed yet(for me).

[Daniel-I]

Thank you for asking the question linub, I am experiencing the same issue as well…

And thank you for the workaround Fabby!

@Fabby

While waiting, you can do the following:

pamac install mlocate
sudo updatedb
locate NameOfFileYouWantToLocate

and after the bug gets fixed:

pamac remove mlocate

[Jaypee]

KDE bug tracker claims it was fixed in kio 5.83, but it still happens in 5.84

[Daniel-I]

I just noticed another alternative app loaded by default in Manjaro KDE Plasma… KFind

I’m not sure that it loads a database like mlocate for performance… seems like it’s crawling the file structure as it searches… but does have a GUI if that’s a nice feature to have. And as you can see it has no issues searching outside the HOME folder.

[Fabby]

As I keep getting on my post to use locate, I’ve marked this answer as the solution to your question as it is by far the best answer you’ll get.

"The process for the filenamesearch protocol died unexpectedly"(since last update)

That’s a coredump, so yes, wait for that to be solved. While waiting, you can do the following: pamac install mlocate sudo updatedb locate NameOfFileYouWantToLocate and after the bug gets fixed: pamac remove mlocate

However, if you disagree with my choice, please feel free to take any other answer as the solution to your question or even remove the solution altogether: You are in control! (If you disagree with my choice, just send me a personal message and explain why I shouldn’t have done this or or if you agree)

P.S. In the future, please don’t forget to come back to your question after your issue has been solved and click the 3 dots below the answer to mark a solution like this below the answer that helped you most:

so that the next person that has the exact same problem you just had will benefit from your post as well as your question will now be in the “solved” status.
