Bug 501308

SUMMARY
When trying to open media files with VLC from an mDNS-discovered non-public SMB share with Dolphin and restarting Dolphin once, VLC fails to open the files.
This only happens when you don't save the credentials when asked.
I noticed that VLC receives a kio_fuse path before restarting.
After the restart it receives an smb:// url, which fails since the share requires credentials.

STEPS TO REPRODUCE
1. Remove saved SMB share from dolphin
2. Close dolphin
3. Delete SMB share credentials in KWalletManager
4. Open Dolphin
5. View the share in the dolphin SMB discovery, login *without* saving the credentials
6. Try to play a media file with VLC from the share, it receives a kio_fuse mounted path
7. Restart dolphin
8. Try to play a media file again, it receives an smb:// url and fails to play it

OBSERVED RESULT
VLC receives a smb:// url

EXPECTED RESULT
VLC should receive a kio_fuse path

ADDITIONAL INFORMATION
I think there's something wrong with the special handling of VLC,
maybe Dolphin thinks after a restart that the share is now a public one, since the credentials were not saved?
I was not able to reproduce it when I clicked that credentials should be saved.
Also only reproducible when using the SMB network discovery.
