Bug 246203

Application: kontact (4.6 pre)
KDE Platform Version: 4.5.00 (KDE 4.5.0) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-19-generic x86_64
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

I was retesting bug #237177 and I noticed that the autocompletion was not working anymore while testing this (I will reopen a bug about this).

The last thing I tested was to add a distribution list as a recipient before printing the email in a .pdf.

It did not print it so I wanted to try again to be sure that it did not work but now Kontact crashes on launch.

Trunk, Svn Rev 1156856

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Aborted
