Keyring and PCManFM

I have the problem that I want to open a ftp location with PCManFM. I can set, and log in with username and password. I select ‘never forget’ and set a bookmark.

After restart when I select the bookmark, I have to open the keyring with my password. But then I get an empty dialog without the stored username / password. I have to type this again.

When I install seahorse I can first start the seahorse, it opens with the GnuPG keys page. I have to go back and select the default keyring and open it with my password. After this procedure I can also use the bookmark of PCManFM without problems.

How can I autostart seahorse with the unlock default keyring dialog on startup? What would be the line to add to the autostart file?
