kontact crashes after login with kwallet asking for password in parallel

[jstammi]

Binary package hint: kontact

Application that crashed: kontact
Version of the application: 4.3.5
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-19-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
1. configure KDE to auto-restore the session having last exited from
2. start kontact: I have it connected to an imap server in local lan with kontact having stored the password in kwallet
3. restart and login again

=>
a) kwallet asks for the password (I guess to provide the imap server credentials to kontact)
b) kontact opens a dialog telling of having found another kontact instance already running
c) crash of contact on confirming the dialog, see report generated below.

This is reproducable at least most times and already for some time being.

On writing this I'm no longer sure if the behaviour differs depending on entering the kwallet password before acknowledging the fialog of vice versa (the latter is for sure the "favorite" order.
