Dear developers,


First of all, I'd like to thank you for your efforts in making really
light and fast web browser. I enjoy using it.


I'm writing you because I want to propose a fix for a segfault I faced
with.

Steps to reproduce:

1. Run `./nsgtk --ca_path=""`
2. Press 'Edit->Preferences'
3. Press 'Close'

Netsurf will segfault.
The proposed patch is attached to this email. It's for version 3.2 or
3.3. I hope you will push it to upstream.


Best regards,
Vitaly
