New crash information added by DrKonqi

dolphin (22.08.3) using Qt 5.15.8

I try to find Samba shares on the network by opening dolphin and browing to `smb:` -- when I do this, it sits for a few seconds (probably probing the network) and then crashes.

I'm on Gentoo, so it's entirely possible I've got some misconfiguration somewhere, or some arcane kernel config setting I've botched, but I don't know where. =)
