           Summary: Kontact crashes at opening kwallet for KNode settings,
                    if KNode is not yet loaded
           Product: kontact
           Version: 4.4.2
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: Warp_7 at gmx.de


Version:            (using KDE 4.4.2)
OS:                Linux
Installed from:    Gentoo Packages

I stumbled upon this while investigating another Kontact bug. I don't have
helpful debug info, but I was able to narrow it down.

Steps to reproduce:
- make sure the default wallet is closed.
- Open Kontact with a component other than KNode.
- Configure Kontact, go to Usenet component -> Accounts
- open settings for an account that contains login information
- BOOM

The crash does not occur if either of the following is true:
- the wallet is already opened (e.g. by accessing it with wallet manager)
- the usenet component was already shown (hence KNode fully loaded)
- an account is edited that doesn't contain login information (authentication
checkbox is disabled), thus doesn't need kwallet

Subsequently, I deleted the wallet, and then Kontact crashes as well instead of
starting the wizard to create a new wallet (which is what KNode does when
editing a contact after the wallet was deleted).
