Application: dolphin (25.04.1) ApplicationNotResponding [ANR]: false Qt Version: 6.9.0 Frameworks Version: 6.14.0 Operating System: Linux 6.11.0-26-generic x86_64 Windowing System: Wayland Distribution: KDE neon 6.3 DrKonqi: 6.3.5 [CoredumpBackend] -- Information about the crash: Dear Dev.-team, I observed a Dolphon crah an have the follwoing add-info: - There were severeal Dolphin windows opened, in total 7, a view with more than one tab. - In one window I executed a search and got the results. - On two of the search results (there were maybe 30 hits) I opened the corresponding folder tabs using right mouse klick on a file. - I retrieved data in those additional tabs and then I decided to manually open one further tab using the button I have added to my default doplhin window appearance. - Immediately after I pressed the button to open this new tab then dolphin crashed. - I tried 3x to reproduce the case but w/o success. - All the other remaining 6 open dolphin windows were not affected. - I use KDE neon with KDE-Plasma-Version 6.3.5, KDE-Framworks 6.14.0, Qt-Version 6.9.0, Kernel 6.11.0-26-generic (64bit), lenovo laptop ThinkPad X1 Yoga Gen 7, 16GB RAM, with 30% memory usage, 16 × 12th Gen Intel® Core™ i5-1240P CPU, no add GPU. - The following apps were active at that moment: Oracle VirtualBox, Firefox, Discover, Kate and Evolution. Hope that helps you. Kind regards, Olaf M.

This is the same backtrace as bug 500101. That was supposedly fixed in 25.04.0. I can't reproduce this on git-master or Neon Testing. You indicated you aren't able to reproduce it right now. If you do see the crash again, please let us know. I'll set this to NEEDSINFO so it will remind us in 15 days. If you see the crash, please set this back to REPORTED. Thanks.
Dear TraceyC, - Thanks for your reply and investigations. Till now the crash did not occur again. - Due to other reasons I've changed 2 days ago the OS from KDE neon to Linux Mint 22.1 but added the KDE plasma desktop it. This plasma version is V5.27.12, not V6.3.5. So I've lost the same environment. However, if I should see the problem again (in the V5... version) I'll definitely update this report. - Can't promise but maybe on my backup laptop is some space left to install the V6... environment to execute further tests. Kind regards and thanks to you and the entire KDE-team for creating such great software, Olaf M.
Thanks for the update. Unfortunately, 5.27.12 is no longer eligible for support from KDE. I don't think the Linux Mint folks provide support for it either. I'm going to close this report for now. If you see the crash again with Dolphin 25.04.0 or later, please re-open this report. Thanks.
