SUMMARY Trying to create new folder with existing folder name, dolphin crashes. STEPS TO REPRODUCE 1. Create new folder with existing folder name 2. May not crash at first try. 3. For me crashed almost every second or first try. OBSERVED RESULT Dolphin Crashes. EXPECTED RESULT Show warning about existing folder. SOFTWARE/OS VERSIONS Linus: Manjaro 20.04 Linux/KDE Plasma: Linux (x86_64) release 5.6.11-1-MANJARO (available in About System) KDE Plasma Version: KDE Frameworks Version: 5.69.0 Qt Version: 5.14.2 (built against 5.14.2) ADDITIONAL INFORMATION Terminal output: [smie@smie-pc ~]$ dolphin kf5.kio.core: We got some errors while running testparm "Error loading services." kf5.kio.core: We got some errors while running 'net usershare info' kf5.kio.core: "Can't load /etc/samba/smb.conf - run testparm to debug it\n" "A folder named /home/smie/a already exists." "A folder named /home/smie/a already exists." Segmentation fault (core dumped)
I cannot reproduce this behavior with Dolphin 20.07.70 on Neon Unstable, despite trying multiple times. If you still experience the behavior, we'd need a backtrace (with debug symbols if possible) to further diagnose and fix the issue.
I am using Dolphin 20.04.0. Still it happens. For some folder it takes 8~9 try, for some folder it takes 1~2 tries. For me creating 'Desktop' folder crashes almost after 1~2 try. I opened Dolphin, pressed F10, typed 'Desktop' and pressed ENTER. Try with my version dolphin. If it doesn't recreate the crash, then I think it will take someday to provide you with the information you need. Because, currently I am using Arch Linux. After searching internet, I found there is no debug symbol in arch. So the only way is to compile it my self. I have compiled some program by my self. But I didn't compiled with debug option enable. Currently I am trying to learn. Thank you for your time.
I have now tried ~20 times, but never succeeded in reproducing the crash. It's not a problem if we have to wait a bit, take your time.

The backtrace does not reveal an issue in Dolphin; it crashes in Qt event processing.
