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.
