Version: 0.4svn1064400 (using KDE 4.3.4) OS: Linux Installed from: Debian testing/unstable Packages When you login on a form with webkit kpart, you have a password stored for that form in kwallet and that webform has autocomplete="off" as an attribute on the input tag, then webkit kpart deletes your password in kwallet. You should rather ignore the autocomplete attribute than deleting users data.
SVN commit 1067185 by adawit: ** Ignore the autocomplete check when saving forms. BUG:220458 M +1 -1 kwebwallet.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1067185
