Application: kioworker (6.17.0) ApplicationNotResponding [ANR]: false Qt Version: 6.9.1 Frameworks Version: 6.17.0 Operating System: Linux 6.15.9-arch1-1 x86_64 Windowing System: Wayland Distribution: "Arch Linux" DrKonqi: 6.4.3 [CoredumpBackend] -- Information about the crash: I'm trying to develop an FTP server (using Rust's unftp) so I started something locally. I then used Dolphin to connect to the FTP server to have a client to test with. I created an empty text file and opened it in Neovim. I made changes and tried to save it, but Neovim told me the file was opened read only (possibly b/c the FTP is so basic right now) and it didn't allow me save. The window then weirdly hang so I just closed it. Then I shut down the FTP server with a simple Ctrl-C which would've abruptly terminated the connection. This caused the crashreport to appear for kioworker, and I believe the stack trace shows it's in the FTP code somewhere. The reporter is unsure if this crash is reproducible. -- Backtrace: Application: kioworker (kioworker), signal: Segmentation fault Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>} Downloading separate debug info for /usr/lib/kf6/kioworker...
