           Summary: Crash on AddressBook::load() / ::asyncLoad() when no
                    address book is accessible
           Product: kaddressbook
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: tokoe@kde.org
        ReportedBy: benedikt@gollatz.net


Version:           CVS HEAD (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 3.3.1 
OS:          Linux

Every time I start KDE, I get an annoying message that tells me that kab2abc crashed. \
When calling up the backtrace I can see that the crash happens in AddressBook:load(). \
There are crashes with similar backtraces when trying to create a new e-mail in kmail \
and typing the adressee's name, when starting kaddressbook or when selecting the \
"Contacts" option from the feature list on the left in kontact (crash in \
AddressBook::asyncLoad() in the two latter cases). Here's a backtrace from a crash \
produced by kaddressbook:

kaddressbook prints this to stderr:

kabc: AddressBook::asyncLoad()

So I guess the crash occours because I don't have an address book:

$ find $HOME -name "*.kab"
$

It seems that something is wrong with AddressBook::d when load() respectively \
asyncLoad() is called and no address book is accessible, because I cannot see any \
other reason why those applications could crash in that function.

I tried deleting $HOME/.kde/share/apps/kabc but it had no effect.
