Application: dolphin (20.12.1) Qt Version: 5.15.2 Frameworks Version: 5.78.0 Operating System: Linux 5.10.10-200.fc33.x86_64 x86_64 Windowing system: Wayland Distribution: Fedora 33 (Thirty Three) -- Information about the crash: - What I was doing when the application crashed: I was modifying an icon theme. One of the themes had a folder symlink called 'devices' that linked to '../icon-theme/devices. The example name of that theme was 'icon-theme-dark' To be more specific in the 22x22 folder. In that folder there was a symlink called 'animations' that linked to '../icon-theme/22x22/animations' And another aclled apps one linking to '../icon-theme/22x22/apps' and more folders and symlinks... I copied all the folders and symlinks to a directory that already has the folder names, but not symlinks, I wrote into the folders and overwrote everything. After that I get a window saying 'could not delete file /home/username/icon-theme/animations.' And I can either retry, skip, skip all and cancel. Retry doesn't crash, but the same windows pops up again. Skipping all doesn't crash and cancelling doesn't crash. After I skip once I get a window saying 'could not delete file /home/username/icon-theme/apps.' Clicking on skip makes dolphin crash. Tried this again and results in the same behaviour I have also crafted a directory which is designed to simulate the actual crash, but I don't really know why it causes to crash. I will upload that to github, see the comments for the link, since I have not uploaded it at the time of writing this. This is the backtrace of that: Application: Dolphin (dolphin), signal: Segmentation fault [KCrash Handler] #4 0x00007f50ba102d64 in QUrl::isValid() const () from /lib64/libQt5Core.so.5 #5

This is the github repo that I made that I was talking about in the description https://github.com/Seplx/Dolphin_crash_copypaste Steps to reproduce: 1. Clone the repo 2. Go to the 'one' folder and copy all of its contents 3. Go to the 'two' folder and paste everything there. 4. You should get a popup, click on skip 5. You should get another popup, click on skip. And it should crash
Upon investigation it seem like it crashes when a symlink tries to "overwrite a folder". If you copy a symlink called a 'folder' and paste it to a folder where there is a folder called 'folder' you would get a prompt to rename the "item" because an item called 'folder' already exists. But the fact that there are folders with the same names that have files with the same names in a directory that you are copying from and to the directory where you are pasting to makes you get the 'File Already Exists' prompt, but you can bypass that one by clicking on 'Write Into' and Clicking on 'Overwrite' next. The folder you are pasting and the folder you are pasting to also must have a folder that is alphabetically behind them and in front of them (so example 'A-Filler' and 'Z-Filler' like I called it in my github repo. Could just be A and Z tho). You also must overwrite 2 folders with 2 symlinks because when it's just 1 you can skip that without a crash, when it's 2 if you skip it twice you get a crash. I crafted a more simple "crasher" based on this that still crashes Dolphin. See: https://github.com/Seplx/Dolphin_crash_copypaste/tree/simpler To make it crash: 1. Clone the repo and go to it in Dolphin 2. Copy everything from the 'COPY' folder and paste it to the 'PASTE' folder. 3. You should get a popup, click on skip 4. You should get another popup, click on skip. And it should crash.
I was able to reproduce this with openSUSE Tumbleweed The backtrace is different though.
