-- Information about the crash:
I accessed an SMB share on my network, typed in my credentials, and crash.
Typing in the incorrect credentials does not crash. It seems to fail to list
the items in the share.
This has happened with both of my network shares, coming from different systems
with different OSes (Synology NAS, Windows 11) and did not happen previously
when I was on (I believe) 24.12.3-1 - I am now on 205.04.0-1.

Additionally, stdout shows this on crash - the exact value in KDirListener
changes each crash, but every other detail is identical.
```
kf.kio.core: Internal error: itemsInUse did not contain
QUrl("smb://tap@taps-vr-pc/")
kf.kio.core: Fatal Error: HUH? Lister KDirLister(0x5e20d7d0bea0) is supposed to
be listing, but has no job!
KCrash: Application 'dolphin' crashing... crashRecursionCounter = 2
Aborted (core dumped)
```

The crash can be reproduced every time.
