Created attachment 130804 [details] After having pressed Close button in Dolphin's Title Bar. SUMMARY Browsing the data subfolder in ~/.zoom, Dolphin freezes after a second or less and I can only interact with the app using Title Bar, having to close Dolphin. As only a few files without extension were strange to me, I tried to reproduce the scenario in its minimal version and the problem is still there. STEPS TO REPRODUCE 1. Create a new directory 2. Create a fifo inside the new directory with mkfifo 3. Open the new directory with Dolphin OBSERVED RESULT Dolphin freezes. Only Title Bar is usable. EXPECTED RESULT Dolphin does not freeze. SOFTWARE/OS VERSIONS Operating System: KDE neon 5.19 KDE Plasma Version: 5.19.4 KDE Frameworks Version: 5.72.0 Qt Version: 5.14.2 Kernel Version: 5.4.0-42-generic OS Type: 64-bit Processors: 4 × Intel® Core™ i5-7600 CPU @ 3.50GHz Memory: 7.7 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 630 ADDITIONAL INFORMATION The freeze also occurs disabling file previews and using any of the view modes.
If the information panel (Shortcut: F11) is enabled, then I can reproduce the freeze.
Ok, if Information Panel is not enabled, the freeze does not occur though the fifo is selected or focused. Now I also have noticed that if the Information Panel is enabled but another, 'regular' file is selected, Dolphin does not freeze. The freeze occurs when the fifo file is hovered: https://streamable.com/5dakvf

Cannot reproduce, even with the information panel enabled. Can you try again?
Hi, Elvis. I have tried and I can no longer reproduce the freeze! Now I am using Dolphin 20.12 with: Operating System: KDE neon 5.20 KDE Plasma Version: 5.20.4 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.2 Kernel Version: 5.4.0-58-generic
Thanks. According to the stacktrace the freeze was in Qt, so it's possible that Qt 5.15 fixed it.
