SUMMARY Dolphin crashes and freezes after starting the search feature. STEPS TO REPRODUCE 1. Press [Ctrl] + [f] to bring up the search feature 2. Type in something to search for 3. Results start to appear 4. Dolphin freezes and there is no way of getting rid of the Dolphin window OBSERVED RESULT Running from the command line, you can see this ``` ... kf.kio.workers.file: readlink failed!

You cannot close the Dolphin window at this stage. `killall`, `kill` also do not work. Using `ps aux | grep dolphin` shows several associated `kioworker` processes running, but killing them does not help in the process to kill Dolphin. EXPECTED RESULT That the search process would run, find items and then finish without freezing Dolphin.

I'm not able to reproduce this with Dolphin 25.08.2 on Plasma 6.5.2 KF 6.19.0 nor on Dolphin built from git-master I'm wondering if there was some detail about the search that caused this. What directory was Dolphin in when this happened? It looks like it's freezing on your system, but may not be crashing. Do you have any coredumps for dolphin? sudo coredumpctl -r

(In reply to Paul Brown from comment #2) > Hm... No coredumps. What does that mean? That means it isn't crashing, it's hanging, which is useful information. Can you run this while Dolphin is frozen? sudo gdb -p $(pidof dolphin) then type bt then press 'c' if it asks you if you want to continue paging Then copy-and-paste the output here. Thanks!

Still impossible to kill the instances of Dolphin too.
Thanks. I'll let those more familiar with Dolphin chime in.
Is it for anything you search, or is it for specific filename/filetype? Do you know what filetypes should appear when searching with the term? Does turning off thumbnails fix the issue? I'm trying to figure out if the hang is caused by thumbnailers or Dolphin itself.
One more question, do you have file-indexing enabled?

Anything, yes. > Do > you know what filetypes should appear when searching with the term? The first couple of times, yes. I was trying something out, so I new what to expect. > Does turning off thumbnails fix the issue? "Thumbnails" as in "previews"? If so, no. Just tried. It froze again. > I'm trying to figure out if the hang is caused by thumbnailers or Dolphin > itself. Right.
