KWallet and KMail issue

Hi, Using full updated standard fc14 (no kde-redhat) I experience a problem with retrieving the saved password in KWallet for sending e-mails. Checking mail works ok. I get the following message: "There have been repeated failed attempts to gain access to a wallet. An application may be misbehaving." I've tried to remove all entries in KWallet, moved config and *.kwl files without succes. Anyone else have seen this? Any ideas how to solve this issue? Thanks, Martin Kho
