Bug 478952

SUMMARY

Previously, I opened a text file on a samba server with an ip on the local network 192.168.0.2.
When launching Kate, a info dialog window appeared saying that the file could not be found at the path smb://admin@192.168.0.2/.
Then a few seconds later the KDE session died, preventing the documents from being saved.
The error is repeated consistently. Reinstallation doesn't help.

STEPS TO REPRODUCE
1. Use Kate to open the file on the smb server.
2. Leave the local network with this server.
3. Launch Kate.
4. Enjoy the fallen KDE.

OBSERVED RESULT
Restarting KDE session

EXPECTED RESULT
Continued work
