SUMMARY I am having some issues in both SFTP and S3 connections in dolphin with KIO I suspect is related to some of the most recent updates, as was previously working flawlessly, will try to investigate further and update. STEPS TO REPRODUCE 1. Install kio-s3 r316.0c31fed-1 and configure it 2. try to connect to a bucket on dolphin 3. try to connect to a sftp host on dolphin OBSERVED RESULT KIO S3: - The process for the s3 protocol died unexpectedly. (connecting to s3://<BUCKET>/<ALIAS>) SFTP: - Internal Error Please send a full bug report at https://bugs.kde.org Could not set host. (connecting to SFTP) EXPECTED RESULT Successful connection SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.2.2 KDE Frameworks Version: 6.7.0 Qt Version: 6.8.0 Kernel Version: 6.11.6-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 16 × Intel® Core™ i9-10885H CPU @ 2.40GHz Memory: 62.4 GiB of RAM Graphics Processor: Quadro T2000 with Max-Q Design/PCIe/SSE2 ADDITIONAL INFORMATION some log messages: kio-fuse[6135]: org.kde.kio.fuse: Root of mount at "s3://" not a directory dolphin[7767]: KCrash: Application 'kioworker' crashing... crashRecursionCounter = 2 systemd-coredump[7790]: Process 7767 (kioworker) of user 1000 terminated abnormally with signal 11/SEGV, pro> systemd[1]: Created slice Slice /system/drkonqi-coredump-processor. systemd[1]: Created slice Slice /system/systemd-coredump. systemd[1]: Started Process Core Dump (PID 7790/UID 0). systemd[1]: Started Pass systemd-coredump journal entries to relevant user for potential DrKonqi handling. systemd-coredump[7791]: [🡕] Process 7767 (kioworker) of user 1000 dumped core.

After investigating more, the SFTP connection fails when using an ssh config Host entry that contains an underscore (_)
(In reply to e from comment #1) > After investigating more, the SFTP connection fails when using an ssh config > Host entry that contains an underscore (_) It should not crash, but underscores(_) are not valid in hostnames. Better change them to dash(-) or something else.
