This is the strangest thing. I put together a wonderful install of Nobara on an external SSD. I have everything I want working to perfection. I decided to clone it to my internal NVME with clonezilla, which went smooth as usual except that when I try to access any SMB share from Dolphin kioworker crashes unexpectedly. What could cause this with just cloning? I did verify that the install on the external still works fine. Thanks.

A number of things can cause this.
But what is great with crashes in Linux nowadays, they leave traces.
Provided you have debuginfod active (most distros have it by default):
coredumpctl gdb -1 kioworker
This will get you a backtrace, telling the circumstances the program crash and allowing a developer patch it eventually.
I’m getting the same error in Fedora 41 with KDE Plasma 6.3.3. Kioworker crashes when I try to access an smb share. Here’s the output from coredumpctl gdb -1 kioworker :

We need more lines, there should be 44 if I am not mistaken, for the trace to be useful.
My bad, here’s the full output:

Thank you for letting us know.
Smb support is implemented in Kde Frameworks, so you updated KF from 6.12 to 6.13, it seems it fixed it.
