kded crashes in KWallet (forgotten KMail password)

This bug is very similar to a KDE bugs currently unpatched. However a similar bug was reported and fixed in Debian as n° 407272.

I can confirm this bug on Feisty. Moreover It usually works bad when I first use KwalletManager.

1) I start my KDE
2) Open Kmail
3) KwalletManager prompts for password. I supply it
4) kded eats 100% of CPU. Kmail freezes.

The only way to continue working is killing kded.

If I kill kded, launch kwalletmanager, open a wallet and then open Kmail.. .all woirks great.

I hope you can help us.

kded hit 1.3% at the most here and KMail and KWallet stay open for roughly 12 to 18 hours a day on this machine.

I sometimes see this problem as well. Kded uses high (95%+) cpu, and all konqueror windows updates stop.

I only see it shortly after I login to kde. I have a large number of konqueror windows, kopete, kontact etc that automatically open and want access to kwallet for passwords. The problem with kded will happen about 20% of the time when I enter the wallet password for the first time. The problem happens as soon as I enter the password. I have waited with the wallet password prompt up for 5 mins to check this.

I have only seen the problem shortly after kde login, I have never seen it after hours or days of using kde when I have to re-open a wallet.

Stephen, I had the same problem. I fixed it by following this advice:

I deleted kwalletrc and logged in again, and no more problem.

I am seeing exactly the same problem in hardy.

KDE has a bugreport: http://bugs.kde.org/show_bug.cgi?id=64671 that is resolved. Maybe there is a regression in Qt in hardy?

Confirm this on Gutsy w. 3.5.9 (but I've had it on 3.5.8 as well, maybe even 3.5.7, not sure).

Log in
KWallet asks for password (for Kopete)
Type in password
-> KDED starts eating 100% of processor power, all KDE applications stop (akregator, kopete, konqueror..)

Killing the kded process solves this.

Looks like that kded likes to eat some resources:

https://bugs.launchpad.net/ubuntu/+source/kdelibs/+bug/196005
(Maybe not duplicates but in all of them 100% of processor resources are used because of 'different reasons')

Funny enough, the KDE bugrep is from year 2003..

Fixed in KDE 4.1 according to the upstream report.
