SUMMARY For a couple of days (I think even before the update to 6.6.3, but I am not sure), weird crashes happen after every startup/login. What always crashes is a kioworker instance. But gwenview also crashes, and I had a krita crash as well, even though it wasn't even started. There was a workaround somewhere here that said to downgrade libexiv, but that didn't work for me. SOFTWARE/OS VERSIONS Operating System: KDE neon User Edition KDE Plasma Version: 6.6.3 KDE Frameworks Version: 6.24.0 Qt Version: 6.10.2 Kernel Version: 6.17.0-19-generic (64-bit) Graphics Platform: Wayland Processors: 6 × AMD Ryzen 5 4500U with Radeon Graphics Memory: 16 GiB of RAM (15.0 GiB usable) Graphics Processor 1: AMD Radeon Graphics Graphics Processor 2: Radeon 550X Series Manufacturer: Acer Product Name: Aspire A515-44G System Version: V1.12 ADDITIONAL INFORMATION Synaptic shows some unmet dependency problems with gdb and libfprint that cannot be solved, so no upgrade is possible. That leads me to believe this might be a problem with KDE Neon, as their team sometimes has troubles with updates.
I forgot to mention: no backtrace is possible. Either clicking on the crash icon in the system tray does nothing (the symbol just disappears), or the download of additional libraries fails. Sending the report also fails.
This is the console output of apt-get dist-upgrade: Reading package lists... Done Building dependency tree... Done Reading state information...

N: Some packages may have been kept back due to phasing.
Another thing: there are multiple crashes of kioworker - up to ten or so.
Probably related to or identical with https://bugs.kde.org/show_bug.cgi?id=518128
As I mentioned in bug 518128, let's use this report for the kioworker crash. As the message at the top of the summary says, if something crashed, we do need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl ? Thanks
Thanks for the help. here's the backtrace: sudo coredumpctl gdb 60180 PID: 60180 (kioworker) UID: 1000 (martin) GID: 1000 (martin) Signal: 11 (SEGV) Timestamp: Thu 2026-03-19 16:06:13 EAT (6 days ago) Command Line: /lib/x86_64-linux-gnu/libexec/kf6/kioworker /usr/lib/x86_64-linux-gnu/qt6/plugins/kf6/kio/thumbnail.so thumbnail "" local:/run/user/1000/dolphinQFiZHP.814.kioworker.socket Executable: /usr/lib/x86_64-linux-gnu/libexec/kf6/kioworker Control Group: /user.slice/user-1000.slice/user@1000.service/app.slice/app-org.kde.dolphin@a82d9a29da4c4949879e4d38e0533083.service Unit: user@1000.service User Unit: app-org.kde.dolphin@a82d9a29da4c4949879e4d38e0533083.service Slice: user-1000.slice Owner UID: 1000 (martin) Boot ID: 25b3a769835542c4aae98f219a595495 Machine ID: 5f71eee45dce498080407e50dfc2b710 Hostname: martin-aspirea51544g Storage: /var/lib/systemd/coredump/core.kioworker.1000.25b3a769835542c4aae98f219a595495.60180.1773925573000000.zst (present) Size on Disk: 3.0M Message: Process 60180 (kioworker) of user 1000 dumped core.

Should I provide abacktrace for every instance of kioworker that crashed?According to coredumpctl --reverse it crashed 22 times.
Just had another look - it was over 500 instances/times that kioworker crashed within a couple of minutes. Other apps had crashes too, like krita, baloo_filemetadata_temp_extractor and gwenview.
