Slow access to public Samba shares in Kubuntu 14.04 - solution

In Dolphin and Konqueror listing shares' content with "smb://host/" takes very long time (minutes) and causes kwalletd to run 100% CPU.

Fix: add any username and password in "System Settings -> Sharing". Log out and log back in. Disabling KDE Wallet subsystem will work too. 

Noticed on i386 and amd64 (both upgrades from earlier versions)
