           Summary: KMail does not start up properly when started with the
                    KDE session
           Product: kmail
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: kde at randomguy3.me.uk


Version:           1.13.0 (SVN r1069428) (using Devel)
Compiler:          gcc version 4.4.2 20091208 (prerelease) (GCC) 
OS:                Linux
Installed from:    Compiled sources

This happens almost every time I log in to KDE when KMail was running at last
logout.  However, sometimes KMail fails to run at all, and sometimes I will get
an "Akonadi failed to start message", causing KMail to quit.

I logged in to a KDE desktop, having last logged out with KMail still running. 
When start-up has finished, no KMail window is visible, and there is no KMail
icon in the notification area (note: I've set KMail to only display in the
notification area when I have unread email).

`pidof kmail`, however, shows that KMail is running, and it responds to D-Bus
messages.

`kquitapp kmail` makes the KMail window appear briefly before KMail quits.

`qdbus org.kde.kmail /kmail/kmail_mainwindow_1 show` shows a window of the
correct size, but almost entirely blank.  All the widgets appear to occupy the
same space in the top left corner of the window.

My set-up for KMail is that I have several IMAP accounts (one running on
localhost, and another four accounts spread across three servers), all with
passwords saved in KWallet, and Akonadi is managing my address book (as a VCF
file).

My best guess is that KMail gets stuck in an inner event loop during startup. 
I'll try to get a backtrace next time this happens to see where.

One final thing: when I do `kquitapp kmail` when KMail is in this state, I get
the following crash:
