Application: kontact (4.4.6)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
I was trying to investigate why my contact groups no longer seem to work, at least in Kontact's auto-complete.  After I clicked through a couple groups in the address book, Kontact crashed with a SIGSEGV.

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