Bug 464050

Application: dolphin (22.12.0)

Qt Version: 5.15.7
Frameworks Version: 5.101.0
Operating System: Linux 6.0.17-300.fc37.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 37 (KDE Plasma)
DrKonqi: 5.26.5 [KCrashBackend]

-- Information about the crash:
I installed samba and tried setting up a network share. It had issues, because my distro (Fedora 37 KDE) seems to not set it up properly. I followed the instructions by creating the missing usershares folder, creating the usershares group, assigning the group ownership of the new folder to that group, adding myself to the group, rebooting and setting a samba user password. Now each time I'm trying to access the "Share" tab in the file properties dolphin crashes. The same thing happens when trying to send a file via Bluetooth. When trying to send a file via KDE Connect from within dolphin, the file never gets sent. There is a message with a progress bar, but it never gets past 0%.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
