           Summary: kontact crash on exit in KABC::AddressBook::findByUid
           Product: kontact
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: pfee at talk21.com


Application that crashed: kontact
Version of the application: 4.3.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I noticed that kontact was using a lot of memory.

"top" showed it's VIRT memory as 1035m and RES as 105m.  I'm not sure if that's
usual or not, but decided to restart kontact to free up some memory.

I quit kontact, the window disappeared, but the process was still visible in
"top", using a lot of CPU, so I presume it had cleanup tasks to do before
exiting completely.

After a delay, perhaps 30 seconds, kontact crashed.

The stack trace shows:
KABC::AddressBook::findByUid (this=0x0, uid=@0x7fffaa7aa950)

I presume "this=0x0" is a sign that a NULL pointer to a KABC::AddressBook has
been dereferenced by way of calling the findByUid() method.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
