           Summary: crash in address autocompletion if akonadi is not
                    available
           Product: kdepimlibs
           Version: 4.4
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: kabc
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: torotil at gmail.com


Version:           4.4 (using KDE 4.4.4) 
OS:                Linux

When akonadi is not available the autocompletion in the To:-address line in
kmail crashes.

Akonadi is often not available for me due to the well known race condition with
the akonadi self-test (I remember this being already reported). Though
ultimately this is the cause - kdepim programs should not crash when akonadi is
not available!

Reproducible: Always

Steps to Reproduce:
1. Start kontact (akonadi self-test fails due to race condition)
2. create new mail
3. go to the address field and start typing until auto-completion starts (the
dropdown box appears)
4. wait a few seconds

Actual Results:  
kontact crashes

Expected Results:  
autocompletion returns with no result.

I currently don't have debug symbols built in so this is all that I can provide
for now:

Application: Kontact (kontact), signal: Segmentation fault
