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

I clicked the button to check for new mails.

- Custom settings of the application:

I have enabled a proxy server in the system configuration using a .pac file.
I might be that the proxy server is not well configured, but it works for http and https.

The crash can be reproduced every time.

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