SUMMARY

Not sure if this is the right place to report this bug. Please, feel free to move it to the right category.

I recently noticed that when trying to open videos from a smb shared folder, VLC will fail saying that "Your input can't be opened: VLC is unable to open the MRL 'smb:/..." if the smb user and password are saved in KWallet. I can only reproduce this issue on a laptop connected over WiFi. In a PC connected over ethernet (and with a fixed IP) it always works. Not sure if it's relevant, but just in case someone tries to reproduce the issue.

Also, this is not a regression, it also happens with Plasma 6.0.5, not just in Plasma 6.1 Beta.

STEPS TO REPRODUCE
1. Open a shared folder with Dolphin writing smb://<IP>/<Folder>
2. Type user and password when asked and click on "Remember password"
3. Try to open video from shared folder with VLC (it works)
4. Reboot computer (or exit session and login back)
5. Open same folder with Dolphin (no user or password is asked as expected)
6. Try to open the same video with VLC (now it fails)
7. Open KWalletManager, search "smb" and delete the entry with the user and password for that shared folder
8. Repeat the steps above, and now it works again
9. If in step 2, password is not saved, and user and password are manually introduced every time, VLC always work

OBSERVED RESULT
VLC can't open videos if user and password are saved in KWallet. Other video players always work (e.g. Dragon Player or mpv).

EXPECTED RESULT
VLC should also work all the times.
