Description Daniel Hahler 2006-10-28 14:41:06 UTC
Version:            (using KDE KDE 3.5.5)
Installed from:    Ubuntu Packages

Kontact crashed, when I've closed it. Before doing so, I've stopped one of the IMAP servers I'm using (for testing).

May be KMail's or Akrekator's fault though. Both appear in the backtrace.
