Rated 5 out of 5 stars

Thnaks tbali editingKDEWalletStorage.js and adding:
get isLoggedIn() {
return true;
}
that fixed it for me.
Back working again.

I discovered google chrome also can use kde wallet now but uses a "pickel" utf16 binary format it would be cool to hack chrome to work like this extenion and allow it to use the shared folder.
Then you could have konqueror, FF and chrome remember all your passwords in one spot.
