Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
If an e-mail contains n > 2 attachments, and I select, using Ctrl+click m attachments with m in [2, n-1], then KMail will crash when the select destination dir. dialog should be shown.

(e.g. select 2 out of 4 attachments, choose "Save as", wait for the attachments to be downloaden (IMAP) and then KMail will crash)

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
The current source language is "auto; currently c".
