mailto: links aren't handled by chromium

[Yuri]

When I click on mailto: link nothing happens.

Screen chrome://chrome/settings/handlers shows no handlers.
On screen chrome://chrome/settings/content option "Allow sites to ask to 
become default handlers for protocols (recommended)" is selected.
kde4 default mailto handler is thunderbird, same as gnome default mailto 
handler.
This works on Ubuntu, thunderbird window shows up when mailto link is 
clicked.

Why mailto links don't work in BSD?
